2020-07-28ARM: mstar: Add reboot supportDaniel Palmer1-0/+7
MStar v7 SoCs support reset by writing a magic value to a register in the "pmsleep" area. This adds a node for using the syscon reboot driver to trigger a reset. Signed-off-by: Daniel Palmer <[email protected]> Signed-off-by: Arnd Bergmann <[email protected]>
2020-07-28ARM: mstar: Add "pmsleep" node to base dtsiDaniel Palmer1-0/+5
This patch adds a node for the pmsleep area so that other drivers can access registers contained within it. Signed-off-by: Daniel Palmer <[email protected]> Signed-off-by: Arnd Bergmann <[email protected]>

2020-07-28ARM: mstar: Adjust IMI size of infinityDaniel Palmer1-0/+4
infinity has 88KB of SRAM at the IMI region. Signed-off-by: Daniel Palmer <[email protected]> Signed-off-by: Arnd Bergmann <[email protected]>
2020-07-28ARM: mstar: Add IMI SRAM regionDaniel Palmer1-1/+7
All MStar v7 SoCs have an internal SRAM region that is between 64KB (infinity2m) and 128KB(infinity3, mercury5). The region is always at the same base address and is used for the second stage loader (MStar IPL or u-boot SPL) and will be used for the DDR self-refresh entry code within the kernel eventually. This patch adds a 128KB region to the SoC and the minimum 64KB SRAM region to the base dtsi. Families with more SRAM will override the size in their family level dtsi.

This userspace program includes UAPI headers exported to usr/include/. 'make headers' always works for the target architecture (i.e. the same architecture as the kernel), so the sample program should be built for the target as well.

Vaibhav explains in the merge commit below why missing v5.8 would be painful and I agreed to try a -rc2 pull because only cosmetics kept this out of -rc1 and his initial versions were posted in more than enough time for v5.8 consideration: 'These patches are tied to specific features that were committed to customers in upcoming distros releases (RHEL and SLES) whose time-lines are tied to 5.8 kernel release. Being able to track the health of an nvdimm is critical for our customers that are running workloads leveraging papr-scm nvdimms. Missing the 5.8 kernel would mean missing the distro timelines and shifting forward the availability of this feature in distro kernels by at least 6 months' Summary: - Fix the visibility of the region 'align' attribute. The new unit tests for region alignment handling caught a corner case where the alignment cannot be specified if the region is converted from static to dynamic provisioning at runtime. - Add support for device health retrieval for the persistent memory supported by the papr_scm driver.

After commit 26d8cde5260b ("pinctrl: freescale: imx: add shared input select reg support"). i.MX7D has two iomux controllers iomuxc and iomuxc-lpsr which share select_input register for daisy chain settings. If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call devm_request_mem_region() for the region <0x30330000-0x3033ffff> for the first time. Then, next time when probe the iomuxc, API devm_platform_ioremap_resource() will also use the API devm_request_mem_region() for the share region <0x30330000-0x3033ffff> again, then cause issue, log like below: [ 0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver [ 0.191742] imx7d-pinctrl 30330000.pinctrl: can't request region for resource [mem 0x30330000-0x3033ffff] [ 0.191842] imx7d-pinctrl: probe of 30330000.pinctrl failed with error -16 Fixes: ba403242615c ("pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'") Signed-off-by: Haibo Chen <[email protected]> Reviewed-by: Dong Aisheng <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Linus Walleij <[email protected]>
