sh: add the sh_ prefix to early platform symbols

2019-10-07T11:50:48+00:00

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_'.

drivers: move the early platform device support to arch/sh

2019-10-07T11:50:47+00:00

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.

serial: sh-sci: Compute the regshift value for SCI ports

2017-01-19T13:17:05+00:00

SCI instances found in SH SoCs have different spacing between registers
depending on the SoC. The platform data contains a regshift field that
tells the driver by how many bits to shift the register offset to
compute its address. We can compute the regshift value automatically
based on the memory resource size, there's no need to pass the value
through platform data.

Fix the sh7750 SCI and sh7760 SIM port memory resources length to ensure
proper computation of the regshift value.

sh: Don't set sh-sci port_reg

2017-01-19T13:17:05+00:00

The driver considers all negative or zero values of the port_reg field
as invalid. The four platforms that set the field to a register address
all use an address higher than 0x7fffffff, which is thus considered by
the driver as invalid. The feature is thus never used, remove it.

The feature could be implemented properly in the future using the
pinctrl and GPIO APIs if desired.

While at it, don't set the field to SCIx_NOT_SUPPORTED (-1) either,
leaving it unset leads to the same result. This will allow removing the
SCIx_NOT_SUPPORTED macro.

sh: Switch to new style TMU device

2014-05-11T10:35:27+00:00

The TMU (Timer Unit) driver implements a new style of platform data that
handles the timer as a single device with multiple channel. Switch from
the old-style platform data to the new-style platform data.
