[PATCH v2 0/4] ARM: ep93xx: various updates

[Florian Fainelli]

Hi all,

This is a rebase of Hartley's original submission:

https://www.spinics.net/lists/arm-kernel/msg564135.html

rebased against v4.13-rc1, I have been using these patches on a TS-7300 board
with 32MB of RAM and everything works fine here as well.

Here is what Hartley wrote in v1:

Here are a couple mach-ep93xx patches that I have been holding on to.
Some of these have been previously posted.

The first patch is needed for 128 MiB version of the TS-7300 board.
That board uses multiple chip selects for the SDRAM and does not boot
with the previous flatmem setup. With the switch, all the other ep93xx
boards I have still work properly.

The second patch has been rebased due to the chip select change in
the spi-ep93xx driver which has been merged.

Patch 3 is just a cosmetic change.

Patch 4 was originally from Florian Fainelli's github ts72xx branch.
It has been updated to the new spi-ep93xx chip select method.

H Hartley Sweeten (4):
  ARM: ep93xx: switch to SPARSEMEM
  ARM: ep93xx: simone: let the mmc_spi driver handle the card detect
  ARM: ep93xx: tidy up TS-72xx Watchdog resources
  ARM: ep93xx: Add lm70 HWMON sensor to TS-72xx boards

[PATCH v2 1/4] ARM: ep93xx: switch to SPARSEMEM

[Florian Fainelli]

From: H Hartley Sweeten <hsweeten@visionengravers.com>

The EP93xx has four chip selects that can be used for the SDRAM memory.
These chip selects are decoded to specify an address domain:

  SDCS3  0x00000000-0x0fffffff with Boot Option ASDO=1
  SDCS0  0xc0000000-0xcfffffff
  SDCS1  0xd0000000-0xdfffffff
  SDCS2  0xe0000000-x0efffffff
  SDCS3  0xf0000000-0xffffffff with Boot Option ASDO=0

Because of the row/column/bank architecture of SDRAM, the mapping of
these memories into the processor's memory space is discontiguous.

Most ep93xx systems only use one of the chip selects. For these systems,
ARCH_HAS_HOLES_MEMORYMODEL has worked fine to handle the discontiguous
memory.

But, some of the TS-72xx boards use multiple chip selects. The TS-7300 in
particular uses SDCS3 (with ASDO=1) and SDCS2. On that system with
ARCH_HAS_HOLES_MEMORYMODEL the SDCS2 memory does not get handled correctly
and results in the system not booting.

Change the EP93xx to ARCH_SPARSEMEM_ENABLE. This handles the discontiguous
memory for all configurations.

This has been tested on the following ep93xx platforms:

EDB9307A with 64 MiB on SDCS0
Vision EP9307 with 64 MiB on SDCS0
TS-7300 with 64 MiB on SDCS3 (with ASDO=1) and 64 MiB on SDCS2
sim.one with 64 MiB on SDCS0

[PATCH v2 2/4] ARM: ep93xx: simone: let the mmc_spi driver handle the card detect

[Florian Fainelli]

From: H Hartley Sweeten <hsweeten@visionengravers.com>

This board uses a GPIO for the MMC card detect. Let the mmc_spi
driver handle it instead of the platform code.

[PATCH v2 3/4] ARM: ep93xx: tidy up TS-72xx Watchdog resources

[Florian Fainelli]

From: H Hartley Sweeten <hsweeten@visionengravers.com>

The ts-72xx watchdog uses two byte sized registers. Tidy up the resource
declaration so that the proper information is shown in /proc/iomem.

Hartley are you sending pull requests to ARM SoC for these

Linus, I don't have my own tree to send a pull request from.
Please put them in one of your trees.
