Revert "pwm: pxa: Use of_match_ptr()" This reverts commit 8468949cddcdbb1b1b1bc552aefceb252078ceb1. The OF match table dummy for non-OF configurations cannot be removed because it is still used by the pxa_pwm_get_id_dt() function. Signed-off-by: Thierry Reding <thierry.reding@gmail.com>

pwm: pxa: Add device tree support This patch adds device tree support to the PXA's PWM driver. Nothing needs to be extracted from the device tree node by the PWM device. Client devices need only specify the period; the per-chip index is implicitly zero because one device node must be present for each PWM output in use. This approach is more convenient due to the wide variability in the number of PWM channels present across the various PXA variants, and is made possible by the fact that the register sets for each PWM channel are segregated from each other. An of_xlate() method is added to parse this single-cell node. The existing ID table is reused for the match table data. Tested on a Palm Treo 680 (both platform data and DT cases).

pwm: pxa: Use module_platform_driver Commit 76abbdde2d95a3807d0dc6bf9f84d03d0dbd4f3d pwm: Add sysfs interface causes a kernel oops due to a null pointer dereference on PXA platforms. This happens because the class added by the patch is registered in a subsys_initcall (initcall4), but the pxa pwm driver is registered in arch_initcall (initcall3). If the class is not registered before the driver probe function runs, the oops occurs in device_add() when the uninitialized pointers in struct class are dereferenced. I don't see a reason that the driver must be an arch_initcall, so this patch makes it a regular module_platform_driver (initcall6), preventing the oops.
