[PATCH v2 0/5] Add support for Sony Xperia SP

[Antony Kurniawan Soemardi]

This patch series adds initial support for the Sony Xperia SP (codename:
sony-huashan), a smartphone based on the Qualcomm MSM8960T SoC. The
MSM8960T is a variant of the MSM8960 featuring an upgraded GPU (Adreno
320 instead of Adreno 225) and a slightly overclocked CPU (1.7GHz
instead of 1.5GHz).

The following changes are included:

1. Adding sdcc3 pinctrl states to ensure micro SD card functionality.
2. Adding gsbi8 node and serial configuration for the MSM8960 SoC.
3. Disabling unused gsbi1 and gsbi5 nodes in the MSM8960 SoC device
   tree.
4. Documentation for the Sony Xperia SP.
5. Initial device tree support for the Sony Xperia SP, including serial
   console, GPIO keys, PM8921 keypad, eMMC, micro SD card, and USB OTG.

This patch series has been tested on the non-LTE variant of the
Xperia SP.

Changes in v2:
- Add explicit bias-pull-up to sdcc3_sleep_state
  The Xperia SP board file actually uses bias-pull-down, but further
  validation is needed to determine if this is a quirk. I checked the
  generic MSM8960 and Samsung Express board files, and both use
  bias-pull-up, so I believe this is the correct approach.
- Fix alignment on gsbi8 node on qcom-msm8960.dtsi
- Add new line before status in gsbi1 and gsbi5 nodes in
  qcom-msm8960.dtsi
- Add short booting notes to the qcom-msm8960-sony-huashan.dts commit
  message
- Link to v1: https://lore.kernel.org/r/20250614-msm8960-sdcard-v1-0-ccce629428b6@smankusors.com

[PATCH v2 1/5] ARM: dts: qcom: msm8960: add sdcc3 pinctrl states

[Antony Kurniawan Soemardi]

Adds sdcc3-default-state and sdcc3-sleep-state pinctrl states for
MSM8960. These are required for devices like Sony Xperia SP to ensure
micro SD card functionality, though they are a no-op on the Samsung
Galaxy Express.

[PATCH v2 2/5] ARM: dts: qcom: msm8960: add gsbi8 and its serial configuration

[Antony Kurniawan Soemardi]

The LTE variant of the MSM8960 SoC has a gsbi8 node used for the
serial console.

That's if the downstream kernel is to be believed, as Xperia SP has
a serial console on gsbi8 even on the non-LTE variant.

[PATCH v2 3/5] ARM: dts: qcom: msm8960: disable gsbi1 and gsbi5 nodes in msm8960 dtsi

[Antony Kurniawan Soemardi]

Not all devices use gsbi1 and gsbi5, so these nodes should be disabled
in the SoC dtsi, following the existing pattern used for gsbi3. The
upstream samsung-expressatt and msm8960-cdp devices already have status
"okay" for these nodes, so this change should not break existing
functionality.

This eliminates the following error messages when gsbi nodes are not
configured in the board's device tree:
[    1.109723] gsbi 16000000.gsbi: missing mode configuration
[    1.109797] gsbi 16000000.gsbi: probe with driver gsbi failed with error -22

(Note: Xperia SP doesn't use gsbi5)

[PATCH v2 5/5] ARM: dts: qcom: add device tree for Sony Xperia SP

[Antony Kurniawan Soemardi]

Add initial device tree support for the Sony Xperia SP (codename:
sony-huashan), a smartphone based on the Qualcomm MSM8960T SoC.

There are two variants of the Xperia SP, one without LTE and one with
LTE. This device tree should work for both variants, though it has only
been tested on the non-LTE variant.

The following are currently supported:
- Serial console support via gsbi8
- GPIO keys for volume up/down buttons
- PM8921 keypad with camera focus/capture keys
- eMMC (sdcc1) and micro SD card (sdcc3) support
- USB OTG support

Other hardware features are not yet implemented.

Booting notes:
Booting a kernel requires using the Sony ELF boot image format, which
embeds the kernel, ramdisk, RPM firmware, and cmdline. This can be
created using the `mkelf` tool. For example:

  python2 mkelf.py -o boot.img \
    kernel+dtb@0x80208000 \
    ramdisk.img@0x81900000 \
    RPM.bin@0x00020000,rpm \
    cmdline.txt@cmdline

The resulting `boot.img` can then be flashed via fastboot. A detailed
guide, including an alternative method, is available at:
https://wiki.postmarketos.org/wiki/Sony_Xperia_SP_(sony-huashan)
