Subject: [RESEND PATCH v3 0/3] sh: make early_platform code SuperH-specific
Date: Mon, 27 Aug 2018 11:06:48 +0200 [thread overview]
Message-ID: <20180827090651.25062-1-brgl@bgdev.pl> (raw)
Message-ID: <20180827090648.m_yoX0KIK8dwwEIrCPUlv_7UI5CJc6ueV78-eruEMWE@z> (raw)
I recently started a discussion about the need for a proper early device
probing mechanism[1]. One that would be based on real platform drivers
and support both platform data and device tree.
While we're far from reaching any consensus on the implementation, Arnd
suggested that I start off by moving the SuperH-specific early platform
drivers implementation to arch/sh[2].
This series is the first attempt at making way for a new, less hacky
implementation.
The first patch removes the last instance of a non-sh driver using the
early_platform API. It can be removed since ARM no longer probes early
drivers.
The second patch moves all the early_platform code to arch/sh.
The last patch prefixes all early_platform symbols with 'sh_'.

v1 -> v2:
- certain drivers are compiled for arm/mach-shmobile too - we need to
add ifdefs for CONFIG_SUPERH around early_platform calls
v2 -> v3:
- added a stub for is_early_platform_device() which always returns false
on non-SuperH architectures
RESEND: rebased on top of v4.18-rc1 and verified that there are no build
failures.
RESEND AGAIN: rebased on top of v4.19-rc1 and verified builds again.

clocksource: timer-ti-dm: remove the early platform driver
registration
platform: move the early platform device support to arch/sh
sh: add the sh_ prefix to early platform symbols
