Subject: [PATCH 00/13 v5] OMAP: GPIO: Implement GPIO in HWMOD way
Date: Fri, 6 Aug 2010 18:04:12 +0530 [thread overview]
Message-ID: <1281098065-24177-1-git-send-email-charu@ti.com> (raw)
This patch series makes OMAP2PLUS specific GPIO implemented in HWMOD
FW way. This is done by implementing GPIO module in platform device model.
This patch series is generated on "origin/pm-wip/hwmods-omap4".
This patch series is created on top of the following two patches:
- OMAP4: HWMOD: Do omap_hwmod_late_init for OMAP4
- musb: Kill board specific pinmux from driver file
http://marc.info/?l=linux-usb&m=127858711304301&w=2
- Revert the following patch:
OMAP: bus-level PM: enable use of runtime PM API for suspend/resume
http://dev.omapzoom.org/?p=swarch/linux-omap-adv.git;a=commitdiff;h=8041359e18e49bf8a3d41f15894db9e476f3a8fc
(or)
Remove the locking in the omap_hwmod_for_each* function
This patch series is tested on OMAP4430 SDP board and OMAP3430 SDP board.
It would be of great help if someone could test the same on OMAP1
and OMAP2 boards.

Version History:
---------------
Comments Fixed in V5:
- Use dev_pm_ops instead of sys_dev_class
- Use runtime suspend/resume hooks for GPIO device
- extend the usage of mod_usage flag to all cpu classes.( Earlier it was
used only for OMAP2PLUS)
- Make gpio_context as part of gpio_bank structure
v4 Series:
Some link for v4 series:
https://patchwork.kernel.org/patch/107411/
Comments Fixed in v4:
- Remove gpio_bank_count from dev_attr field and derive it from
hwmod class iteration count
- Add TODOs for future omap gpio code cleanup related activity
- Rename gpio's platform_data 'method' to 'bank_type'
- Rename gpio's platform_data 'gpio_bank_bits' to 'gpio_bank_width'
- Add 'rev' field to gpio class in hwmod datbase and get 'bank_type'
based on 'rev' field
- Filename removed from file description when a new file is created
Comments Fixed in v3:
- .module_offs populated in hwmod structures
- If not defined CONFIG_PM_RUNTIME is not handled in GPIO driver
- No changes to mach-omap2/clockxxxx-data.c to handle clocks by dev ptr
as it is taken care using clock get by name in hwmod & omap_device layer
- Using "ick" instead of "arm_gpio_ck" for OMAP15xx clock
- SoC base addresses moved to plat-omap/omapXXXX.h that should be
used only by the omap_hwmod_xxxx_data.c file
- OMAP2/3 hwmod structures naming convention changed as it is
followed in OMAP4
- omap24xx_gpio_init() uses cpu_is_omap24xx() instead of separate
checks for 2420 & 2430 in OMAP2 specific init call (mach-omap layer)
- Reason for using postcore_initcall is added to patch description for
the patch "OMAP: GPIO: Introduce support for OMAP2PLUS chip GPIO init"
- Comments added for usage of dbck_flag and other elements
in dev_attr structure
- Uses dev_dbg() and dev_err() instead of pr_dbg() and pr_err()
- Corrects the gpio clock details in OMAP4 hwmod database

http://www.mail-archive.com/linux-omap@vger.kernel.org/msg28933.html
Comments Fixed in V2:
- GPIO dev attr was added for SoC specific chip info (eg., gpio bank count)
- Removed omap_gpio_init() usage from board files
- platform_get_resource() used instead of pdata->base for
OMAP2+ base addresses
- postcore_initcall used for gpio init instead of making
GPIO as an early platform device. SoC specific gpio_init
needs to be done before machine_init functions access gpio
APIs. Hence making SoC specific gpio_init as postcore_initcall.
- getting gpio dbck is moved to omap_set_gpio_debounce()
instead of doing it in probe

http://www.mail-archive.com/linux-omap@vger.kernel.org/msg28183.html
Highlights in v1:
- Introduces SoC specific functions at mach-omap layer
- Implements GPIO as a platform device
- Make gpio an early device and make it implemented in
HWMOD FW adapted way for OMAP2PLUS
