Patch descriptions need to make sense. This one does not. I've fixed it for you this time, but please take more care in the future. - Paul From: Philip Avinash Date: Wed, 2 Jan 2013 18:54:48 +0530 Subject: [PATCH] ARM: OMAP: AM33xx hwmod: Corrects PWM subsystem HWMOD entries EQEP IP block integration data is not present in HWMOD data. Also address ranges specified for EACP & EHRPWM are not correct & HWMOD flags of ADDR_TYPE_RT are 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.
