2022-09-19gpio: mlxbf2: Use generic_handle_irq_safe()Sebastian Andrzej Siewior
On PREEMPT_RT enabled kernels the demultiplex interrupt handler is force threaded and runs with interrupts enabled. The invocation of generic_handle_irq() with interrupts enabled triggers a lockdep warning due to a non-irq safe lock acquisition. Instead of disabling interrupts on the driver level, use generic_handle_domain_irq_safe().

2022-09-19platform/x86: msi-laptop: Change DMI match / alias strings to fix module ↵Hans de Goede
autoloading On a MSI S270 with Fedora 37 x86_64 / systemd-251.4 the module does not properly autoload. This is likely caused by issues with how systemd-udevd handles the single quote char (') which is part of the sys_vendor / chassis_vendor strings on this laptop. As a workaround remove the single quote char + everything behind it from the sys_vendor + chassis_vendor matches. This fixes the module not autoloading.

2022-09-19wifi: wcn36xx: Add RX frame SNR as a source of system entropyBryan O'Donoghue
The signal-to-noise-ratio SNR is returned by the wcn36xx firmware for each received frame. SNR represents all of the unwanted interference signal after filtering out the fundamental frequency and harmonics of the frequency. Noise can come from various electromagnetic sources, from temperature affecting the performance hardware components or quantization effects converting from analog to digital domains. The SNR value returned by the WiFi firmware then is a good source of entropy. Other WiFi drivers offer up the noise component of the FFT as an entropy source for the random pool e.g. commit 2aa56cca3571 ("ath9k: Mix the received FFT bins to the random pool") I attended Jason's talk on sources of randomness at Plumbers and it occurred to me that SNR is a reasonable candidate to add.

2022-09-19habanalabs/gaudi2: increase hard-reset sleep time to 2 secTomer Tayar
The access to the device registers is blocked during hard reset, until preboot runs and allows the access to specific registers, including the PSOC BTM_FSM register which is used to know when the reset is done. Between the reset request and until this register is polled there is a small delay of 500 msec which is not enough for F/W to process the reset and for preboot to run, so the register might be accessed while it is blocked. To avoid it, increase the delay to 2 sec. Signed-off-by: Tomer Tayar <ttayar@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>

i.MX93 LPCG is different from i.MX8M CCGR. Although imx_clk_hw_gate4_flags is used here, it not strictly match i.MX93. i.MX93 has such design: - LPCG_DIRECT use BIT0 as on/off gate when LPCG_AUTHEN CPU_LPM is 0 - LPCG_LPM_CUR use BIT[2:0] as on/off gate when LPCG_AUTHEN CPU_LPM is 1 The current implementation suppose CPU_LPM is 0, and use LPCG_DIRECT BIT[1:0] as on/off gate. Although BIT1 is touched, actually BIT1 is reserved. And imx_clk_hw_gate4_flags use mask 0x3 to determine whether the clk is enabled or not, but i.MX93 LPCG only use BIT0 to control when CPU_LPM is 0. So clk disabled unused during kernel boot not able to gate off the unused clocks. To match i.MX93 LPCG, introduce imx93_clk_gate.

The CCM ROOT AUTHEN register WHITE_LIST indicate: Each bit in this field represent for one domain. Bit16~Bit31 represent for DOMAIN0~DOMAIN15 respectively. Only corresponding bit of the domains is set to 1 can change the registers of this Clock Root. i.MX93 DID is 3, so if BIT(3 + WHITE_LIST_SHIFT) is 0, the clk should be set to read only. To make the imx93_clk_composite_flags be reusable, add a new parameter named did(domain id); Signed-off-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Ye Li <ye.li@nxp.com> Reviewed-by: Jacky Bai <ping.bai@nxp.com> Reviewed-by: Abel Vesa <abel.vesa@linaro.org> Signed-off-by: Abel Vesa <abel.vesa@linaro.org> Link: https://lore.kernel.org/r/20220830033137.4149542-5-peng.fan@oss.nxp.com
2022-09-19clk: imx: clk-composite-93: check slice busyPeng Fan
i.MX93 CCM ROOT STAT register has a SLICE_BUSY bit: indication for clock generation logic is applying new setting. 0b - Clock generation logic is not busy. 1b - Clock generation logic is applying new setting. So when set parent/rate/gate, need check this bit. Introduce specific ops to do the work.

2022-09-19wifi: rtw89: 8852c: add multi-port ID to TX descriptorPo-Hao Huang
Update tx descriptor settings so broadcast packets on other ports can be issued properly when DTIM count is 0. Before this, all broadcast packets are sent via port 0 and won't be transmitted correctly.
