Subject: [PATCH v5 02/12] ARM: OMAP: AM33xx hwmod: Corrects PWM subsystem HWMOD entries
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.
Signed-off-by: Philip, Avinash <avinashphilip@...com>
---
Changes since v4:
- Split the HWMOD patches to handle correction of PWMi
subsystem correction.
