Subject[PATCH 0/5] Support the codec and wifi/bt for rk3036 Kylin board
Message-ID<qIrAd-2af-9@gated-at.bofh.it>
Add the needed device for kylin board.

--------------
This series patches have the following decriptions:

PATCH[1/5]:
ARM: dts: set the pinctrl default setting for i2s

The kylin will hang in system when enable the i2s,
we need set the pinctrl default setting for i2s firstly.
--------------

PATCH[2/5]:
ARM: dts: add the sound codec for kylin board

Let the codec works.

RT5616 driver is landed in Mark branch.
(https://git.kernel.org/cgit/linux/kernel/git/broonie/sound.git/commit/
?h=for-next&id=b1d15059957d33d111e0ed38724a6b2c5caac790)

Maybe need wait the below patch be merged firstly.
(add an of_match table: https://patchwork.kernel.org/patch/7901951/
rt5616 document: https://patchwork.kernel.org/patch/7901971/)
---------------

PATCH[3/5]:
ARM: dts: rockchip: enable the high speed on sdio for kylin board

This patch is solving the wifi work frequency.
37.5MHz frequency for rk3036.

The wifi throughput:

iperf -s -i 1
...
[  4] 116.0-117.0 sec  2.88 MBytes  24.1 Mbits/sec
[  4] 117.0-118.0 sec  2.99 MBytes  25.0 Mbits/sec
[  4] 118.0-119.0 sec  3.01 MBytes  25.2 Mbits/sec
[  4] 119.0-120.0 sec  2.89 MBytes  24.2 Mbits/sec
[  4]  0.0-120.4 sec   332 MBytes  23.1 Mbits/sec
----------------

PATCH[4/5]:
ARM: dts: add the wifi/bt regulator for kylin board

Add the wifi/bt regulator for wifi module, let the module work on bootup.

Yep, this patch is based on olof patch[0].
patch[0]:
https://patchwork.kernel.org/patch/3510571/
----------------

PATCH[5/5]:
ARM: dts: enable the uart0 for bluetooth module

Enable the uart0 for BT module working.
----------------

Note: that's seem the wifi driver has not landed in mainline.
This driver has existed in rockchip github develop4.1.

#1296655 — [PATCH 3/5] ARM: dts: rockchip: enable the high speed on sdio for kylin board

Subject[PATCH 3/5] ARM: dts: rockchip: enable the high speed on sdio for kylin board
Message-ID<qIrAg-2af-45@gated-at.bofh.it>
In reply to#1296653
We want to the higher speed for wifi module working.

Bootup kernel log:
...
mmc_host mmc0: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz,
actual 37125000HZ div = 0)

or run 'cat /sys/kernel/debug/clk/clk_summary |grep phase -C 1' to check
Otherwise, the mmc0 will run 400khz defalult value to work.
