* bus: ti-sysc: suppress err msg for timers used as clockevent/sourceGrygorii Strashko2020-11-191-1/+1
| | | | | | | | | | | | | | | GP Timers used as clockevent/source are not available for ti-sysc bus and handled by Kernel timekeeping core. Now ti-sysc produces error message every time such timer is detected: "ti-sysc: probe of 48040000.target-module failed with error -16" Such messages are not necessary, so suppress them by returning -ENXIO instead of -EBUSY.

* bus: ti-sysc: Fix bogus resetdone warning on enable for cpswTony Lindgren2020-10-261-0/+3
| | | | | | | | | | | | | | | | | Bail out early from sysc_wait_softreset() just like we do in sysc_reset() if there's no sysstatus srst_shift to fix a bogus resetdone warning on enable as suggested by Grygorii Strashko <grygorii.strashko@ti.com>. We do not currently handle resets for modules that need writing to the sysstatus register. If we at some point add that, we also need to add SYSS_QUIRK_RESETDONE_INVERTED flag for cpsw as the sysstatus bit is low when reset is done as described in the am335x TRM "Table 14-202 SOFT_RESET Register Field Descriptions" Fixes: d46f9fbec719 ("bus: ti-sysc: Use optional clocks on for enable and wait for softreset bit") Suggested-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* bus: ti-sysc: Fix reset status check for modules with quirksTony Lindgren2020-10-261-9/+15
| | | | | | | | | | | | | | | | | | | Commit d46f9fbec719 ("bus: ti-sysc: Use optional clocks on for enable and wait for softreset bit") started showing a "OCP softreset timed out" warning on enable if the interconnect target module is not out of reset. This caused the warning to be often triggered for i2c and hdq while the devices are working properly. Turns out that some interconnect target modules seem to have an unusable reset status bits unless the module specific reset quirks are activated. Let's just skip the reset status check for those modules as we only want to activate the reset quirks when doing a reset, and not on enable. This way we don't see the bogus "OCP softreset timed out" warnings during boot.

This one is added together with the official Evaluation platform. - Qualcomm: The Snapdragon SDM630 platform is a family of mid-range mobile phone chips from 2017 based on Cortex-A53 or Kryo 260 CPUs. A total of five end-user products are added based on these, all Android phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra. - Renesas: RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G family, and apparently closely related to the RZ/G2N and RZ/G2M models we already support but has a faster GPU and additional on-chip peripherals. It is added along with the HopeRun HiHope RZ/G2H development board A small number of new boards for already supported SoCs also debut: - Allwinner sunxi: Only one new machine, revision v1.2 of the Pine64 PinePhone (non-Android) smartphone, containing minor changes compared to earlier versions. - Amlogic Meson: WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box - Aspeed: EthanolX is AMD's EPYC data center rerence platform, using an ASpeed AST2600 baseboard management controller. - Mediatek: Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook based on the MT8183 (Helio P60t) SoC. - Nvidia Tegra: ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android tablets from around 2012 using Tegra 3 and Tegra 2, respectively. Thanks to PostmarketOS, these can now run mainline kernels and become useful again. The Jetson Xavier NX Developer Kit uses a SoM and carrier board for the Tegra194, their latest 64-bit chip based on Carmel CPU cores and Volta graphics. - NXP i.MX: Five new boards based on the 32-bit i.MX6 series are added: The MYiR MYS-6ULX single-board computer, and four different models of industrial computers from Protonic. - Qualcomm: MikroTik RouterBoard 3011 is a rackmounted router based on the 32-bit IPQ8064 networking SoC Three older phones get added, the Snapdragon 808 (msm8992) based Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running Windows Phone, and the Snapdragon 810 (msm8994) based Sony Xperia Z5. - Renesas: In addition to the HiHope RZ/G2H board mentioned above, we gain support for board versions 3.0 and 4.0 of the earlier RZ/G2M and RZ/G2N reference boards. Beacon EmbeddedWorks adds another SoM+Carrier development board for RZ/G2M. - Rockchips: Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it is based on, using the high-end 32-bit rk3288 SoC. Notable updates to existing platforms are usually for added on-chip peripherals, including: - ASpeed AST2xxx (various) - Allwinner (cpufreq, thermal, Pinephone touchscreen) - Amlogic Meson (audio, gpu dvdfs, board updates) - Arm Versatile - Broadcom (board updates for switch ports, Raspberry pi clock updates) - Hisilicon (various) - Intel/Altera SoCFPGA (various) - Marvell Armada 7xxx/8xxx (smmu) - Marvell MMP (GPU on mmp2/mmp3) - Mediatek mt8183 (USB, pericfg) - NXP Layerscape (VPU, thermal, DSPI) - NXP i.MX (VPU, bindings, board updates) - Nvidia Tegra194 (GPU) - Qualcomm (GPU, Interconnect, ...) - Renesas R-Car (SPI, IPMMU, board updates) - STMicroelectronics STM32 (various) - Samsung Exynos (various) - Socionext Uniphier (updates to serial, and pcie) - TI K3 (serdes, usb3, audio, sd, chipid) - TI OMAP (IPU/DSP remoteproc changes, dropping platform data)" * tag 'arm-dt-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (605 commits) arm64: dts: meson: odroid-n2: add jack audio output support arm64: dts: meson: odroid-n2: enable audio loopback ARM: dts: berlin: Align L2 cache-controller nodename with dtschema arm64: dts: qcom: Add Microsoft Lumia 950 (Talkman) device tree arm64: dts: qcom: Add Xiaomi Libra (Mi 4C) device tree arm64: dts: qcom: msm8992: Add RPMCC node arm64: dts: qcom: msm8992: Add PSCI support. arm64: dts: qcom: msm8992: Add PMU node arm64: dts: qcom: msm8992: Add BLSP2_UART2 and I2C nodes arm64: dts: qcom: msm8992: Add SPMI PMIC arbiter device arm64: dts: qcom: msm8992: Add a SCM node arm64: dts: qcom: msm8992: Add a proper CPU map arm64: dts: qcom: bullhead: Move UART pinctrl to SoC arm64: dts: qcom: bullhead: Add qcom,msm-id arm64: dts: qcom: msm8992: Fix SDHCI1 arm64: dts: qcom: msm8992: Modernize the DTS style arm64: dts: qcom: Add support for Sony Xperia Z5 (SoMC Sumire-RoW) arm64: dts: qcom: Move msm8994-smd-rpm contents to lg-bullhead. arm64: dts: qcom: msm8994: Add support for SMD RPM arm64: dts: qcom: msm8992: Add a label to rpm-requests ...
