Subject: [PATCH v10 11/27] ARM: davinci: da8xx: add new USB PHY clock init using common clock framework
Date: Wed, 9 May 2018 12:25:50 -0500 [thread overview]
Message-ID: <20180509172606.29387-12-david@lechnology.com> (raw)
In-Reply-To: <20180509172606.29387-1-david@lechnology.com>
This adds the new USB PHY clock init in mach-davinci/usb-da8xx.c using
the new common clock framework drivers.
The #ifdefs are needed to prevent compile errors until the entire
ARCH_DAVINCI is converted.
Signed-off-by: David Lechner <david@lechnology.com>

v10 changes:
- none
v9 changes:
- none
v8 changes:
- rebased on "ARM: davinci: DA8XX: fix oops in USB PHY driver due to stack
allocated platform platform_data"
v7 changes:
- register platform device instead of registering clocks directly
- USB PHY clocks now treated as single device instead of registering them
separately
v6 changes:
- rename stuff to match changes in "clk: davinci: New driver for TI DA8XX USB
PHY clocks"
- take advantage of syscon lookup changes in "mfd: syscon: Add syscon_register()
function"
