2021-05-14net: dsa: qca8k: handle qca8k_set_page errorsAnsuel Smith1-7/+26
With a remote possibility, the set_page function can fail. Since this is a critical part of the write/read qca8k regs, propagate the error and terminate any read/write operation.

2021-05-14net: hns3: refactor out RX completion checksumHuazhong Tan3-32/+22
Only when RXD advanced layout is enabled, in some cases (e.g. ip fragments), the checksum of entire packet will be calculated and filled in the least significant 16 bits of the unused addr field. So refactor out the handling of RX completion checksum: adjust the location of the checksum in RX descriptor, and use ptype table to identify whether this kind of checksum is calculated.

2021-05-14net: hns3: support RXD advanced layoutHuazhong Tan12-26/+393
Currently, the driver gets packet type by parsing the L3_ID/L4_ID/OL3_ID/OL4_ID from RX descriptor, it's time-consuming. Now some new devices support RXD advanced layout, which combines previous OL3_ID/OL4_ID to 8bit ptype field, so the driver gets packet type by looking up only one table, and L3_ID/L4_ID become reserved fields. Considering compatibility, the firmware will report capability of RXD advanced layout, the driver will identify and enable it by default. This patch provides basic function: identify and enable the RXD advanced layout, and refactor out hns3_rx_checksum() by using ptype table to handle RX checksum if supported.

2021-05-14drm/panfrost: devfreq: Disable devfreq when num_supplies > 1Nicolas Boichat1-0/+9
GPUs with more than a single regulator (e.g. G72 on MT8183) will require platform-specific handling for devfreq, for 2 reasons: 1. The opp core (drivers/opp/core.c:_generic_set_opp_regulator) does not support multiple regulators, so we'll need custom handlers. 2. Generally, platforms with 2 regulators have platform-specific constraints on how the voltages should be set (e.g. minimum/maximum voltage difference between them), so we should not just create generic handlers that simply change the voltages without taking care of those constraints. Disable devfreq for now on those GPUs.

Mohammed reports (https://bugzilla.kernel.org/show_bug.cgi?id=213029) the commit e4ab4658f1cf ("clocksource/drivers/hyper-v: Handle vDSO differences inline") broke vDSO on x86. The problem appears to be that VDSO_CLOCKMODE_HVCLOCK is an enum value in 'enum vdso_clock_mode' and '#ifdef VDSO_CLOCKMODE_HVCLOCK' branch evaluates to false (it is not a define). Use a dedicated HAVE_VDSO_CLOCKMODE_HVCLOCK define instead.

2021-05-14spi: Don't have controller clean up spi device before driver unbindSaravana Kannan1-3/+3
When a spi device is unregistered and triggers a driver unbind, the driver might need to access the spi device. So, don't have the controller clean up the spi device before the driver is unbound. Clean up the spi device after the driver is unbound.

The rest of the code refers to version 1.2 of the MIPI D-PHY specification. But this comment refers to 2.1, while a sub comment of the function refers to 1.2 again. Replace 2.1 with 1.2.

2021-05-14phy: Allow a NULL phy name for devm_phy_get()Rob Herring1-7/+9
For a single PHY, there's no reason to have a phy-names entry in DT. The DT specific get functions allow for this already, but devm_phy_get() WARNs in this case. Other subsystems also don't warn in their get functions. Let's drop the WARN for DT case in devm_phy_get().

While IS_ENABLED() is perfectly fine for CONFIG_* symbols, it is not for other symbols such as __BIG_ENDIAN that is provided directly by the compiler. Switch to use CONFIG_CPU_BIG_ENDIAN instead of __BIG_ENDIAN.
