dvco_rst is part of peripheral clocks and all peripheral clocks are
restored by clk-tegra210 driver which happens before dfll driver resume.
So dfll rst thru part of peripheral clock enable is set prior to dfll
reset deassertion

If it is legal to omit the timings in DT, then tegra_pmc_parse_dt() need to be corrected if
there is assumption of 0 meaning that values are undefined in DT.

Actually, readl does the rmb() and it should be a more correct variant of fencing because it
actually ensures that the write reached hardware. I suppose that something like fence_udelay

I don't see what enables the DFLL clock because it should be enabled by the CPUFreq driver
on resume from suspend and resume happens after resuming of the DFLL driver.

POR value for these timing registers is not 0 and has default timings
based on chip design and on top of that based on platform HW components
charge/discharge timings there's a need to increase these timings so
support for programming these thru DT is needed and these values have
effect only in LP0.

tegra_clk_register_super_mux which uses tegra_clk_super_mux_ops doesn't
do divider rate programming.
I believe you are referring to sclk_divider, cclklp_divider,
cclkg_divider...
these are registered as clk_divider and are restored during clk_divider
resume.

by the time restore happens, peripheral clocks are enabled but held in
reset state.
For non-boot clocks, doing divider programming before parent source is
preferred.
For sdmmc clock, programming parent before divisor is allowed.
Also, clk_sdmmc_mux_set_rate gets parent MUX selection thru register
read so restoring parent prior to this will have right divisor based on
rate and parent.

By the time dfll resume happens, dfll controller clock will already be

* [PATCH 1/7] [RFC] ARM: remove Intel iop33x and iop13xx support
From: Arnd Bergmann @ 2019-08-09 16:33 UTC (permalink / raw)
To: soc
Cc: Arnd Bergmann, Russell King, Dan Williams, Vinod Koul,

linux-kernel, dmaengine, linux-gpio, linux-i2c
In-Reply-To: <20190809162956.488941-1-arnd@arndb.de>
There are three families of IOP machines we support in Linux: iop32x
(which includes EP80219), iop33x and iop13xx (aka IOP34x aka WP8134x).
All products we support in the kernel are based on the first of these,
iop32x, the other families only ever supported the Intel reference
boards but no actual machine anyone could ever buy.
While one could clearly make them all three work in a single kernel
with some work, this takes the easy way out, removing the later two
platforms entirely, under the assumption that there are no remaining
users.
Earlier versions of OpenWRT and Debian both had support for iop32x
but not the others, and they both dropped iop32x as well in their 2015
releases.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
---
I'm just guessing that iop32x is still needed, and the other two are
not. If anyone disagrees with that assessment, let me know so we
can come up with an alternative approach.

* [PATCH 7/7] ARM: iop32x: merge everything into mach-iop32x/
From: Arnd Bergmann @ 2019-08-09 16:33 UTC (permalink / raw)
To: soc
Cc: Arnd Bergmann, Russell King, Dan Williams, Vinod Koul,
Linus Walleij, Bartosz Golaszewski, linux-arm-kernel,
linux-kernel, dmaengine, linux-gpio, linux-i2c
In-Reply-To: <20190809163334.489360-1-arnd@arndb.de>
Various bits of iop32x are now in their traditional locations in plat-iop,
mach-iop/include/mach/ and in include/asm/mach/hardware. As nothing
outside of the iop32x mach code references these any more, this can all
be moved into one place now.
The only remaining things in the include/mach/ directory are now the
NR_IRQS definition, the entry-macros.S file and the the decompressor
uart access. After the irqchip code has been converted to SPARSE_IRQ
and GENERIC_IRQ_MULTI_HANDLER, it can be moved to ARCH_MULTIPLATFORM.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* [PATCH 4/7] dma: iop-adma: allow building without platform headers
From: Arnd Bergmann @ 2019-08-09 16:33 UTC (permalink / raw)
To: soc
Cc: Arnd Bergmann, Russell King, Dan Williams, Vinod Koul,
Linus Walleij, Bartosz Golaszewski, linux-arm-kernel,
linux-kernel, dmaengine, linux-gpio, linux-i2c
In-Reply-To: <20190809163334.489360-1-arnd@arndb.de>
Now that iop3xx and iop13xx are gone, the iop-adma driver no
longer needs to deal with incompatible register layout defined
in machine specific header files.
Move the iop32x specific definitions into drivers/dma/iop-adma.h
and the platform_data into include/linux/platform_data/dma-iop32x.h,
and change the machine code to no longer reference those.
The DMA0_ID/DMA1_ID/AAU_ID macros are required as part of the
platform data interface and still need to be visible, so move
those from one header to the other.

* [PATCH 6/7] ARM: iop32x: make mach/uncompress.h independent of mach/hardware.h

To: soc

In-Reply-To: <20190809163334.489360-1-arnd@arndb.de>
All supported uarts use the same address: IQ80321_UART and IQ31244_UART
are both defined to the default value of 0xfe800000. By using that as
the address unconditionally, all dependencies on other machine headers
can be avoided.

* [PATCH 3/7] dma: iop-adma: use correct printk format strings

To: soc
Cc: Arnd Bergmann, Russell King, Dan Williams, Vinod Koul,

In-Reply-To: <20190809163334.489360-1-arnd@arndb.de>
When compile-testing on other architectures, we get lots of warnings
about incorrect format strings, like:
drivers/dma/iop-adma.c: In function 'iop_adma_alloc_slots':
drivers/dma/iop-adma.c:307:6: warning: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]
drivers/dma/iop-adma.c: In function 'iop_adma_prep_dma_memcpy':
>> drivers/dma/iop-adma.c:518:40: warning: format '%u' expects argument of type 'unsigned int', but argument 5 has type 'size_t {aka long unsigned int}' [-Wformat=]
Use %zu for printing size_t as required, and cast the dma_addr_t
arguments to 'u64' for printing with %llx. Ideally this should use
the %pad format string, but that requires an lvalue argument that
doesn't work here.

Will rename as valid_mask.
some bits in these registers are undefined and is not good to write to
these bits as they can cause pslverr.

To prevent glitchless frequency switch, Tegra clock programming
recommended sequence is to change MUX control or divisor or both with
the clocks running.
Actual state of clocks before suspend are restored later after all PLL's
and peripheral clocks are restored.

USB PLL restore is independent to all other clocks restore. So this can
be done either before clk_restore_context or even after.

* [PATCH v2 05/13] gpio: lpc32xx: allow building on non-lpc32xx targets
From: Arnd Bergmann @ 2019-08-09 14:40 UTC (permalink / raw)
To: soc
Cc: Vladimir Zapolskiy, Sylvain Lemieux, linux-arm-kernel,
linux-kernel, Arnd Bergmann, Linus Walleij, Bartosz Golaszewski,
linux-gpio
In-Reply-To: <20190809144043.476786-1-arnd@arndb.de>
The driver uses hardwire MMIO addresses instead of the data
that is passed in device tree. Change it over to only
hardcode the register offset values and allow compile-testing.
Acked-by: Sylvain Lemieux <slemieux.tyco@gmail.com>
