Changes for v7 of this patch series:
- Use clocksource_register_hz
- Add mxs namespace for the missing ones
- Use CLKCTRL_RESET_CHIP over RTC_WATCHDOG to implement arch_reset
- Define naked pad and introduce validity bits for mA/vol/pull
to ease the pad modification
- List all pad definitions at once generated from Freescale
pinmux Excel sheet
- Add more comments for timrot instance used for MX23 and MX28
- Use HW_TIMROT_TIMCOUNTn for v1 to avoid confusion
- Detect timrot version by reading register HW_TIMROT_VERSION
- Switch over to use gpiolib __gpio_to_irq()
- Fix some checkpatch warnings
The full change log could be found in the version history of
following individual patch.
[PATCH v7 03/15] ARM: mxs: Add reset routines
[PATCH v7 04/15] ARM: mxs: Add interrupt support
[PATCH v7 05/15] ARM: mxs: Add low-level debug UART support

- The mxs wdog is implemented in RTC block.
- There is a generic software reset routine for most modules on mxs.

Add Interrupt Collector (ICOLL) support for MXS-based.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
---
Change for v7:
- Add namespace for ICOLL_VBASE
Changes for v3:
- icoll.c: add #include <linux/io.h> as it's removed from mx23.h
and mx28.h
- Change inclusion of hardware.h to mxs.h
- Move writing to HW_ICOLL_VECTOR from icoll.c icoll_ack_irq()
into entry-macro.S get_irqnr_and_base
- icoll.c: add more words into comments for level 0 irq ack
- mx23 and mx28 share the same icoll base address, so hard-coding
of the address is ok
- entry-macro.S: define and use HW_ICOLL_STAT_OFFSET over 0x70
Changes for v2:
- Get icoll base in get_irqnr_preamble
- Check the case of single SoC build and use hard-coding address if possible

There are 2 versions of the timrot on Freescale MXS-based SoCs.
The v1 on MX23 only gets 16 bits counter, while v2 on MX28
extends the counter to 32 bits.
The implementation uses two timers, one for clock_event and
another for clocksource. MX28 uses timrot 0 and 1, while MX23
uses 0 and 2.

Changes for v7:
- Use clocksource_register_hz suggested by Rusell
- Add more comments for timrot instance used for MX23 and MX28
- Use HW_TIMROT_TIMCOUNTn for v1 to avoid confusion
- Detect timrot version by reading register HW_TIMROT_VERSION
- Add namespace for clockevent_device and clockevent_mode
- Add namespace for timer_base
Changes for v6:
- Use __mxs_setl() and __mxs_clrl() for bit set/clear
Changes for v4:
- Change inclusion of hardware.h to mxs.h
- Use two timers on MX28 also to simpify timrotv2_set_next_event()
- MX23 and MX28 share the common timrot base address, so it can be
a hard-assignment.
- Pass &clockevent_mxs to mxs_timer_interrupt via mxs_timer_irq.dev_id
- Fix code of setting far-far future
- Change printk to pr_info and pr_err
- Change timrotv2 min_delta_ns to 0xf
Changes for v3:
- Use term clock_event over next_event and clocksource over get_cycles
- Split BV_TIMROT_TIMCTRLn_SELECT__32KHZ_XTAL into two definitions for v1 and v2 respectively
- Turn timrot_get_cycles() into timrotv1_get_cycles() and timrotv2_get_cycles()
- Turn timrot_set_next_event() into timrotv1_set_next_event() and timrotv2_set_next_event()
- Skip flag IRQF_DISABLED
- Remove unncessary IRQ disabling in mxs_set_mode()
- Change shift of clocksource_mxs to 17
Changes for v2:
- Fix a bug in timrot_set_next_event(). It should read
HW_TIMROT_RUNNING_COUNTn to get the current counts.

MXS-based SoCs implement gpio support in block PINCTRL.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
---
Changes for v7:
- Switch over to use gpiolib __gpio_to_irq()
Changes for v6:
- Use __mxs_setl() and __mxs_clrl() for bit set/clear
- Rename functions for not using leading underscore
- Add mxs_ to some functions name to align naming scheme
- Introduce variables pin_mask and pin_addr to make code look better
- Remove PINCTRL_PIN2IRQ from irq_stat assignment
- Add comment for clearing status bit in IRQSTAT
- Set up irq handler before registering gpio chip
Changes for v5:
- Leave PIN2IRQ set when disabling gpio IRQ to avoid
losting interrupt
Changes for v3:
- include/mach/gpio.h: remove the inclusion of hardware.h
- gpio.c: change inclusion of hardware.h to mx23.h plus mx28.h
- Remove spinlock totally since SET/CLE can be used in all the
gpio register access
Changes for v2:
- Create arch/arm/mach-mxs/gpio.h to accommodate stuff private for mach-mxs
- Use GPIO_INT_LEV_MASK and GPIO_INT_POL_MASK instead of constant
- Remove both edges IRQ support which is not needed
- Use SET and CLR register of PINCTRL_DOE in _set_gpio_direction()
- Use pr_info over printk(KERN_INFO)

MXS-based SoCs implements iomux functions in block PINCTRL.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>

Changes for v7
- Define naked pad and introduce validity bits for mA/vol/pull
to ease the pad modification
- List all pad definitions at once generated from Freescale
pinmux Excel sheet
Changes for v6:
- Use __mxs_setl() and __mxs_clrl() for bit set/clear
Changes for v5:
- Change iomux_cfg_t from u64 to u16
- Add namespace MXS_ to shift, mask, and pad definitions
- Use SET/CLR register for 1 bit setting
- Get "if" and "{" at the same line
- Remove space in middle of tabs
- Change "setups" to "configures" in comments
Changes for v3:
- Change iomux_cfg_t to u64 to facilitate adding platform specific
pad_ctrl settings to an existing pad definition
- Change inclusion of hardware.h to mxs.h
- Get iomux_base a hard-assignment in mxs_iomux_setup_pad(), since
mx23 and mx28 share the common pinctrl base adress and it's only
used in mxs_iomux_setup_pad().
- Remove EXPORT_SYMBOL and the static of mxs_iomux_setup_pad()
Changes for v2:
- Define iomux_cfg_t as u64
- Turn mxs_iomux_setup_pad() into a static function
- Fix a bug in mxs_iomux_setup_pad(), muxsel starts at offset 0x100 than 0 of pinctrl block.

From: Shawn Guo @ 2010-12-18 13:39 UTC (permalink / raw)
To: linux-arm-kernel
Add clock for MXS-based SoCs, MX23 and MX28.
Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
---
Changes for v7:
- Remove one tailing tab in clock-mx23.c and clock-mx28.c
Changes for v5
- Fix PARENT_RATE_SHIFT from left to right
Changes for v3:
- Fix freq overflow in clock-mx23.c as well
- Fix the overflow using SH_DIV and shifting 8 bits
- Remove the inclusion of hardware.h and include mx23.h/mx28.h
Changes for v2:
- Shift pll0_clock freq 480MHz in children freq computation to avoid overflow
- Fix fec_clk to stand for fec clock than IEEE1588 time clock
- Add pll2_clk into clock lookups, as it's fec phy clock and needs to be on before reset phy

This wasn't here before
I'm not sure if this is worth a v8.

I would keep these on a single line. YMMV, so for me no need for a v8.
I will test this series later on hardware, and if no show stoppers
appear I'd say this is ready to be merged. The (maybe) remaining issues
can then be resolved in follow up patches.

My intension was to keep the pad configuration on different line from
the naked pad. I will keep this comment and that extra space one
in mind, and address them later.
Thanks for the review and test effort.

Hi Shawn,
I discovered this weekend that the DUART is just an amba-pl011 which
is already supported in mainline. So we should use the existing
infrastructure here.

We should be able to use the AMBA identification signature to distinguish at
runtime, no?

We should use asm/hardware/debug-pl01x.S, like the other users:
wsa at katana:~/Kernel/linux-2.6/arch/arm$ g debug-pl01x
include/asm/hardware/debug-pl01x.S:1:/* arch/arm/include/asm/hardware/debug-pl01x.S

Auto-detection could be used here, too?

Just tested it, and it works. Will do in v8. Thanks for the comment.

I'm afraid not. How do you expect the detection is done, by reading
some register like we are doing in system.c? Which register
specifically? If the register gets different address between
mx23 and mx28, we need to utilize the current mechanism to
distinguish the address anyway.

I am not sure which register you mean in system.c?

The signature of the amba device (base + size - 0x20). You can check
drivers/amba/bus.c how it checks for the signature.

We could simply test both locations and see where it is present?
Kind regards,

Is there any problem of simply using arch_id here? I do not see
significant benefit of using the detection you suggest here
over the current way.

Ah, sorry, I thought you meant auto-detection was not possible in
debug.S as well (and there it is worthwhile so mx23 and mx28 can be
built into one kernel). For uncompress.h, the gain is nothing major,
true. One would save to add custom boards there just to match the base
address, but well...
Kind regards,
Wolfram
