Driver updates for ARM SoCs, including a couple of newly added drivers: - A new driver for the power management controller on TI Keystone - Support for the prerelease "SCPI" firmware protocol that ended up being shipped by Amlogic in their GXBB SoC. - A soc_device can now be matched using a glob from inside the kernel, when another driver wants to know the specific chip it is running on and cannot find out from DT, firmware or hardware. - Renesas SoCs now support identification through the soc_device interface, both in user space and kernel. - Renesas r8a7743 and r8a7745 gain support for their system controller - A new checking module for the ARM "PSCI" (not to be confused with "SCPI" mentioned above) firmware interface. - A new driver for the Tegra GMI memory interface - Support for the Tegra firmware interfaces with their power management controllers As usual, the updates for the reset controller framework are merged here, as they tend to touch multiple SoCs as well, including a new driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp interface. The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and Rockchips SoCs see some further updates. Conflicts: - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB - drivers/soc/renesas/Makefile: multiple files got added, keep all in logical sorting -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAWFMaGWCrR//JCVInAQLs5RAA3I1I8/R+pd5jfMaAB8Od3S4g8YSqIDjC EIOoDPx9GDV70+cGs4ea+L9bfGs3ePGivCtcbftNsLDAueQ2jKMa3ShqxA/MMbJE rWQi/ARaDFY0nHL8VPWq7XyYwwrah+/gKBr8UhkaKI0vy6DBqxyCknrS2kgF88rv DVs2wnRvDM7GVUax0JDzuySR7BXJIuUfS78jPMESASbTQktsZTFUyH+osiqHtptD M5bPC8rxOeZXljt3DOvXSdK9rVnji/A3nznY4r3tlt805eaOA7CzjVSsY27WQel0 63uj+FgE+eM0sECIxpkNbH/HHq2V4QkUoy3fk0xPkzRbllBBpS+UieGamTnPJup8 wf5uiH1IqLLLV9F/504S92fp0pgFPpOGYWZnBDlIbh3aGq4tMjIRqRYMTyCT02hN +b54v0SuImFiN6p8HMS1ugYQ+1m9TU40b5pZkzkTJbSQOMm6oi3j0A0orXU/TPKd FVMrlUyfh+yu+vs1hGWLs1+mBjFnxXzSc8yJeaCdX4MvCY5/aVJZ+cwq4Bk+1YU5 9Qhkeo5JV/l9FlrjxomnEq3l/WV/pFmj7JRZsb1BM88m+5LYUf2lv11b5B4FvrTd yx8SSpe3+ofIijdNbJ8IywF6y0OXF6UnrlouOVdSIp+wPs+pibdU/5gQep16pvqd WW6sVWn6quA= =6dP8 -----END PGP SIGNATURE----- Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, including a couple of newly added drivers: - A new driver for the power management controller on TI Keystone - Support for the prerelease "SCPI" firmware protocol that ended up being shipped by Amlogic in their GXBB SoC. - A soc_device can now be matched using a glob from inside the kernel, when another driver wants to know the specific chip it is running on and cannot find out from DT, firmware or hardware. - Renesas SoCs now support identification through the soc_device interface, both in user space and kernel. - Renesas r8a7743 and r8a7745 gain support for their system controller - A new checking module for the ARM "PSCI" (not to be confused with "SCPI" mentioned above) firmware interface. - A new driver for the Tegra GMI memory interface - Support for the Tegra firmware interfaces with their power management controllers As usual, the updates for the reset controller framework are merged here, as they tend to touch multiple SoCs as well, including a new driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp interface.

For this to work, either your bootloader needs to enable the CDMM

region at an unused physical address on the boot CPU, or else your

platform code needs to implement mips_cdmm_phys_base() (see
