Subject: [PATCH 2/3] arm: mach-omap2: omap_hwmod_43xx_data: add hwmod support for tscadc on am43x-evm
This patch adds hwmod support for tscadc to work on am43xx-evm. The am33xx
hwmod structures of tscadc has been moved to ipblock_data so that it can
be reused in am43xx. The clock domain names are separately set for am33xx
and am43xx. Thus tscadc dt entries can now be added to am43xx board
dt files.
