Merge tag 'qcom-drivers-for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers
Qualcomm driver updates for 5.12 The socinfo driver gains support for dumping information about the platform's PMICs, as well as new definitions for a number of platforms. The LLCC driver gains SM8250 support, AOSS QMP gains SM8350 support and the RPMPD driver gains support for MSM8994 power domains. In addition to this it contains a few minor fixes in the ocmem, rpmh and llcc drivers. * tag 'qcom-drivers-for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: ocmem: don't return NULL in of_get_ocmem soc: qcom: socinfo: Remove unwanted le32_to_cpu() soc: qcom: aoss: Add SM8350 compatible drivers: soc: qcom: rpmpd: Add msm8994 RPM Power Domains soc: qcom: socinfo: Fix an off by one in qcom_show_pmic_model() soc: qcom: socinfo: Fix off-by-one array index bounds check soc: qcom: socinfo: Add MDM9607 IDs soc: qcom: socinfo: Add SoC IDs for APQ/MSM8998 soc: qcom: socinfo: Add SoC IDs for 630 family soc: qcom: socinfo: Open read access to all for debugfs soc: qcom: socinfo: add info from PMIC models array soc: qcom: socinfo: add several PMIC IDs soc: qcom: socinfo: add qrb5165 SoC ID soc: qcom: rpmh: Remove serialization of TCS commands soc: qcom: smem: use %*ph to print small buffer dt-bindings: soc: qcom: convert qcom,smem bindings to yaml drivers: qcom: rpmh-rsc: Do not read back the register write on trigger soc: qcom: llcc-qcom: Add support for SM8250 SoC soc: qcom: llcc-qcom: Extract major hardware version dt-bindings: msm: Add LLCC for SM8250 Link: https://lore.kernel.org/r/20210204052258.388890-1-bjorn.andersson@linaro.org Signed-off-by: Arnd Bergmann <arnd@arndb.de>

-Qualcomm Shared Memory Manager binding
-
-This binding describes the Qualcomm Shared Memory Manager, used to share data
-between various subsystems and OSes in Qualcomm platforms.
-
-- compatible:
- Usage: required
- Value type: <stringlist>
- Definition: must be:
- "qcom,smem"
-
-- memory-region:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: handle to memory reservation for main SMEM memory region.
-
-- qcom,rpm-msg-ram:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: handle to RPM message memory resource
-

-= EXAMPLE
-The following example shows the SMEM setup for MSM8974, with a main SMEM region
-at 0xfa00000 and the RPM message ram at 0xfc428000:
-
- reserved-memory {
- #address-cells = <1>;
