Subject: [PATCH 18/22] ARM: omap1: clk: rework 'struct clk'

From: Arnd Bergmann <[email-masked]>
Date: Thu, 8 Aug 2019 23:41:28 +0200

To get closer to the way the common_clk code works, rename
the omap1 struct clk to 'omap1_clk', and add trivial 'clk_hw'
and 'clk' wrapper to work like the generic counterparts.
