Subject: [PATCH 0/7] HWMOD fixes for AM33xx PWM submodules and device tree nodes.
Date: Wed, 2 Jan 2013 18:54:47 +0530 [thread overview]
Message-ID: <1357133094-30806-1-git-send-email-avinashphilip@ti.com> (raw)
This patch series is being part of [1] and resubmitting on top of 3.8-rc1 to
make it to 3.9.
In AM33xx PWM sub modules like ECAP, EHRPWM & EQEP are integrated to
PWM subsystem. All these submodules shares the resources (clock) & has
a clock gating register in PWM Subsystem. So a parent PWM subsystem
driver is created. To support PWM subsystem driver, parent child
relation is created in HWMOD entry in patch #2.
In addition EHRPWM module requires explicit clock gating from control
module. Hence add clock node for tbclk handling in patch #4.
Patch #3 to support common clock migration for AM33xx.
Also Device tree nodes populated to support parent child relation
between PWMSS, ECAP & EHRPWM submodules (patch #5, 6 & 7).
This patch series based on linux_omap/master [2] and tested for
backlight with ECAP on AM335x-evm & AM335x-evmsk.
