2024-09-05Input: zforce_ts - stop treating VDD regulator as optionalDmitry Torokhov
This regulator is not optional from the controller point of view, so stop treating it as such. For hard-wired designs that omit the regulator from their device trees regulator subsystem will create a dummy instance. This may introduce unnecessary delay of 100us in case of dummy regulator, but if it is important the driver should be marked as using asynchronous probing to avoid even longer delays waiting for the command completions. Also use usleep_range() instead of udelay() to avoid spinning.

2024-09-05Input: zforce_ts - make parsing of contacts less confusingDmitry Torokhov
Zforce touch data packet consists of a byte representing number of contacts followed by several chunks with length of 9 bytes representing each contact. Instead of accounting for the leading byte by increasing offset of each field in contacts by one introduce a pointer to contact data and point it appropriately. This avoids awkward constructs like: point.prblty = payload[9 * i + 9]; which makes it seem like there is off-by-one error, in favor of more straightforward: point.prblty = p[8]; Tested-by: Andreas Kemnade <andreas@kemnade.info> # Tolino Shine2HD Link: https://lore.kernel.org/r/20240824055047.1706392-11-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2024-09-02Merge tag 'scmi-updates-6.12' of ↵Arnd Bergmann
https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.12 Few main features include: 1. SCMI transport as stand-alone drivers Currently the SCMI transport layer is being built embedded into in the core SCMI stack. Some of these transports, despite being currently part of the main SCMI module, are indeed also registered with different subsystems like optee or virtio, and actively probed also by those. This leads to a few awkward and convoluted tricks to properly handle such interactions at boot time in the SCMI stack. This change adds the new logic to the core SCMI stack so that each existing transport is transitioned to be a standi-alone driver. With that all the probe deferral and awkward retries between the SCMI core stack and the transports has been removed, since no more needed. 2. Support for obtaining transport descriptors from the devicetree SCMI platform firmwares might have different designs depending on the platform. Some of the transport descriptors rely on such design. E.g. the maximum receive channel timeout value might vary depending on the specific underlying hardware and firmware design choices. This change adds support for max-rx-timeout-ms property to describe the transport needs of a specific platform design. It will be extended in the future to obtain other such hardware/firmware dependent transport related descriptors. 3. NXP i.MX95 specific SCMI vendor protocol extensions SCMI specification allows vendor or platform-specific extensions to the interface. NXP i.MX95 System Manager(SM) that implements SCMI extends the interface to implement couple of vendor/platform specific protocol, namely: a. Battery Backed Module(BBM) Protocol This protocol is intended provide access to the battery-backed module. This contains persistent storage (GPR), an RTC, and the ON/OFF button. The protocol can also provide access to similar functions implemented via external board components. b. MISC Protocol for misc settings This includes controls that are misc settings/actions that must be exposed from the SM to agents. They are device specific and are usually define to access bit fields in various mix block control modules, IOMUX_GPR, and other GPR/CSR owned by the SM. 4. SCMI debug/tracking metrics Since SCMI involves interaction with the entity(software, firmware and/or hardware) providing services or features, it is quite useful to track certain metrics(for pure debugging purposes) like how many messages were sent or received, were there any failures, what kind of failures, ..etc. This feature adds support for the same via debugfs. Apart from these main features, there are some miscellaneous updates, fixes and cleanups. * tag 'scmi-updates-6.12' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (31 commits) rtc: support i.MX95 BBM RTC input: keyboard: support i.MX95 BBM module firmware: imx: Add i.MX95 MISC driver firmware: arm_scmi: Add initial support for i.MX MISC protocol firmware: arm_scmi: Add initial support for i.MX BBM protocol firmware: arm_scmi: Add NXP i.MX95 SCMI documentation dt-bindings: firmware: Add i.MX95 SCMI Extension protocol firmware: arm_scmi: Replace comma with the semicolon firmware: arm_scmi: Replace the use of of_node_put() to __free(device_node) firmware: arm_scmi: Fix trivial whitespace/coding style issues firmware: arm_scmi: Use max-rx-timeout-ms from devicetree dt-bindings: firmware: arm,scmi: Introduce property max-rx-timeout-ms firmware: arm_scmi: Remove const from transport descriptors firmware: arm_scmi: Simplify with scoped for each OF child loop firmware: arm_scmi: Update various protocols versions firmware: arm_scmi: Remove legacy transport-layer code firmware: arm_scmi: Make VirtIO transport a standalone driver firmware: arm_scmi: Make OPTEE transport a standalone driver firmware: arm_scmi: Make SMC transport a standalone driver firmware: arm_scmi: Make MBOX transport a standalone driver ...

Commit 8bccf667f62a ("Input: cypress_ps2 - report timeouts when reading command status") uncovered an existing problem with cypress_ps2 driver: it tries waiting on a PS/2 device waitqueue without using the rest of libps2. Unfortunately without it nobody signals wakeup for the waiting process, and each "extended" command was timing out. But the rest of the code simply did not notice it. Fix this by switching from homegrown way of sending request to get command response and reading it to standard ps2_command() which does the right thing.
