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

* [PATCH v3 2/3] platform: move the early platform device support to arch/sh

To: linux-arm-kernel
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
SuperH is the only user of the current implementation of early platform
device support. We want to introduce a more robust approach to early
probing. As the first step - move all the current early platform code
to arch/sh.
In order not to export internal drivers/base functions to arch code for
this temporary solution - copy the two needed routines for driver
matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c.
Also: call early_platform_cleanup() from subsys_initcall() so that it's
called after all early devices are probed.

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
SuperH is the only user of the current implementation of early platform
device support. We want to introduce a more robust approach to early
probing. As the first step - move all the current early platform code
to arch/sh.
In order not to export internal drivers/base functions to arch code for
this temporary solution - copy the two needed routines for driver
matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c.
Also: call early_platform_cleanup() from subsys_initcall() so that it's
called after all early devices are probed.

* [PATCH v3 2/3] platform: move the early platform device support to arch/sh
@ 2018-05-04 13:27 ` Bartosz Golaszewski

To: linux-arm-kernel
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
SuperH is the only user of the current implementation of early platform
device support. We want to introduce a more robust approach to early
probing. As the first step - move all the current early platform code
to arch/sh.
In order not to export internal drivers/base functions to arch code for
this temporary solution - copy the two needed routines for driver
matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c.
Also: call early_platform_cleanup() from subsys_initcall() so that it's
called after all early devices are probed.

* [PATCH v3 3/3] sh: add the sh_ prefix to early platform symbols
2018-05-04 13:27 ` Bartosz Golaszewski

To: linux-arm-kernel
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Old early platform device support is now sh-specific. Before moving on
to implementing new early platform framework based on real platform
devices, prefix all early platform symbols with 'sh_'.

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Old early platform device support is now sh-specific. Before moving on
to implementing new early platform framework based on real platform
devices, prefix all early platform symbols with 'sh_'.

* [PATCH v3 3/3] sh: add the sh_ prefix to early platform symbols
@ 2018-05-04 13:27 ` Bartosz Golaszewski
0 siblings, 0 replies; 38+ messages in thread
From: Bartosz Golaszewski @ 2018-05-04 13:27 UTC (permalink / raw)
To: linux-arm-kernel
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Old early platform device support is now sh-specific. Before moving on
to implementing new early platform framework based on real platform
devices, prefix all early platform symbols with 'sh_'.
