* ARM: pxa: move mach/*.h to mach-pxa/Arnd Bergmann2022-05-071-1/+1

* ARM: pxa: lubbock: pass udc irqs as resourceArnd Bergmann2022-05-071-1/+11
| | | | | | | | | | | | | | | Lubbock is the only machine that has three IRQs for the UDC. These are currently hardcoded in the driver based on a machine header file. Change this to use platform device resources as we use for the generic IRQ anyway.

* ARM: pxa: split up mach/hardware.hArnd Bergmann2022-04-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mach/hardware.h is included in lots of places, and it provides three different things on pxa: - the cpu_is_pxa* macros - an indirect inclusion of mach/addr-map.h - the __REG() and io_pv2() helper macros Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h headers, then change all the files that use mach/hardware.h to include the exact set of those three headers that they actually need, allowing for further more targeted cleanup. linux/soc/pxa/cpu.h can remain permanently exported and is now in a global location along with similar headers. pxa-regs.h and addr-map.h are only used in a very small number of drivers now and can be moved to arch/arm/mach-pxa/ directly when those drivers are to pass the necessary data as resources.

This basically renamed the existing 'struct clk' to 'struct clk_hw', and introduced a new 'struct clk'. This change will break anyone using clk_add_alias() with the common clk code enabled. Thankfully, the intersection of users of clk_add_alias() and those using the common clk code is practically zero, but this is something which should be fixed to keep the code sane. The problem is that clk_add_alias() does this: r = clk_get(...); l = clkdev_alloc(r, ...); clk_put(...); which causes the alias to store a pointer to 'r', which has been freed. The original patch set tried to work around this problem incorrectly - at clk_get() time, it tried to convert the struct clk to a struct clk_hw, and then creating a new struct clk from that. Clearly, if the original struct clk has been freed, then we have a use-after-free bug. We have other places in the tree which do something similar, so this series also addresses those locations too. This series addresses this problem by converting clkdev to store and use the clk_hw pointer. This allows clk_get() to only have to create it's per-user struct clk from the clk_hw. We can also get to the desired clk_hw at clk_add_alias() or clk lookup creation time, when the struct clk is "alive". We also perform some cleanups of the code: - replacing looped calls to clkdev_add() with clkdev_add_table() - replacing open-coded lookup allocation (which should have been using clkdev_alloc()) and subsequent clkdev_add() with clkdev_create() - replacing open-coded clk_add_alias() with clk_add_alias()" * 'for-linus-clk' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: clk: s2mps11: use clkdev_create() ASoC: migor: use clkdev_create() ARM: omap2: use clkdev_add_alias() ARM: omap2: use clkdev_create() ARM: orion: use clkdev_create() ARM: lpc32xx: convert to use clkdev_add_table() SH: use clkdev_add_table() clkdev: add clkdev_create() helper clkdev: const-ify connection id to clk_add_alias() clkdev: get rid of redundant clk_add_alias() prototype in linux/clk.h clkdev: drop __init from clkdev_add_table() clk: update clk API documentation to clarify clk_round_rate() clkdev: use clk_hw internally

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

For enabling CPU idle event, CPU arch code should call ledtrig_cpu() stub to trigger idle start or idle end event. These patches convert old style LED driver in arch/arm to gpio_led or new led driver interface. Against 3.5 release and build successfully for all the machines. Test ledtrig-cpu driver on OMAP4 Panda board. v9 --> v10 * fix compiling issue on versatile_defconfig reported by Russell King * rebase to 3.5 kernel and move patches to new git tree v8 --> v9: * use mutex to replace rw_sema pointed out by Tim Gardner * add a new struct led_trigger_cpu * add lock_is_inited to record mutex lock initialization v6 --> v7: * add a patch to unify the led-trigger name * fix some typo pointed * use BUG_ON to detect CPU numbers during building stage v5 --> v6: * replace __get_cpu_var() to per_cpu() * remove smp_processor_id() which is wrong with for_each_possible_cpu() * test on real OMAP4 Panda board * add comments about CPU hotplug in the CPU LED trigger driver v4 --> v5: * rebase all the patches on top of latest linux-next * replace on_each_cpu() with for_each_possible_cpu() * add some description of ledtrig_cpu() API * remove old leds code from driver nwflash.c, which should use a new led trigger then * this trigger driver can be built as module now v3 --> v4: * fix a typo pointed by Jochen Friedrich * fix some building errors * add Reviewed-by and Tested-by into patch log v2 --> v3: * almost rewrote the whole ledtrig-cpu driver, which is more simple * every CPU will have a per-CPU trigger * cpu trigger can be assigned to any leds * fix a lockdep issue in led-trigger common code * other fix according to review v1 --> v2: * remove select operations in Kconfig of every machines * add back supporting of led in core module of mach-integrator * solidate name scheme in ledtrig-cpu.c * add comments of CPU_LED_* cpu led events * fold patches of RealView and Versatile together * add machine_is_ check during assabet led driver init * add some Acked-by in patch logs * remove code for simpad machine in machine-sa11000, since Jochen Friedrich introduced gpiolib and gpio-led driver for simpad * on Assabet and Netwinder machine, LED operations is reversed like: setting bit means turn off leds clearing bit means turn on leds * add a new function to read CM_CTRL register for led driver * 'for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds: ARM: use new LEDS CPU trigger stub to replace old one ARM: mach-sa1100: retire custom LED code ARM: mach-omap1: retire custom LED code ARM: mach-pnx4008: remove including old leds event API header file ARM: plat-samsung: remove including old leds event API header file ARM: mach-pxa: retire custom LED code char: nwflash: remove old led event code ARM: mach-footbridge: retire custom LED code ARM: mach-ebsa110: retire custom LED code ARM: mach-clps711x: retire custom LED code of P720T machine ARM: mach-integrator: retire custom LED code ARM: mach-integrator: move CM_CTRL to header file for accessing by other functions ARM: mach-orion5x: convert custom LED code to gpio_led and LED CPU trigger ARM: mach-shark: retire custom LED code ARM: mach-ks8695: remove leds driver, since nobody use it ARM: mach-realview and mach-versatile: retire custom LED code ARM: at91: convert old leds drivers to gpio_led and led_trigger drivers led-triggers: create a trigger for CPU activity Conflicts: arch/arm/mach-clps711x/p720t.c arch/arm/mach-sa1100/leds-cerf.c arch/arm/mach-sa1100/leds-lart.c Let's hope this is the last time we pull this and it doesn't cause more trouble.
