[PATCH 1/7] ARM: OMAP: AM33xx hwmod: Corrects PWM subsystem HWMOD entries

Wed Jan 2 08:24:48 EST 2013


EQEP entry is HWMOD entry is not present in HWMOD entry. Also address
ranges specified for EACP & EHRPWM is not correct & HWMOD flags of
ADDR_TYPE_RT is added to PWM subsystem register address space. This
patch
1. Corrects register address mapping for ECAP & EHRPWM
2. Removes  HWMOD flags in PWM submodule register address space.
3. Adds EQEP HWMOD entries.
