2024-03-05mei: vsc: Assign pinfo fields in variable declarationSakari Ailus1-8/+8
Assign all possible fields of pinfo in variable declaration, instead of just zeroing it there.

2024-03-05mei: vsc: Don't use sleeping condition in wait_event_timeout()Sakari Ailus1-5/+8
vsc_tp_wakeup_request() called wait_event_timeout() with gpiod_get_value_cansleep() which may sleep, and does so as the implementation is that of gpio-ljca. Move the GPIO state check outside the call.

2024-03-05mei: vsc: Call wake_up() in the threaded IRQ handlerSakari Ailus1-2/+2
The hard IRQ handler vsc_tp_irq() is called with a raw spinlock taken. wake_up() acquires a spinlock, a sleeping lock on PREEMPT_RT. This leads to sleeping in atomic context. Move the wake_up() call to the threaded IRQ handler vsc_tp_thread_isr() where it can be safely called.

2024-02-28iio: adc: rockchip_saradc: use mask for write_enable bitfieldQuentin Schulz1-2/+2
Some of the registers on the SARADCv2 have bits write protected except if another bit is set. This is usually done by having the lowest 16 bits store the data to write and the highest 16 bits specify which of the 16 lowest bits should have their value written to the hardware block. The write_enable mask for the channel selection was incorrect because it was just the value shifted by 16 bits, which means it would only ever write bits and never clear them. So e.g. if someone starts a conversion on channel 5, the lowest 4 bits would be 0x5, then starts a conversion on channel 0, it would still be 5. Instead of shifting the value by 16 as the mask, let's use the OR'ing of the appropriate masks shifted by 16. Note that this is not an issue currently because the only SARADCv2 currently supported has a reset defined in its Device Tree, that reset resets the SARADC controller before starting a conversion on a channel. However, this reset is handled as optional by the probe function and thus proper masking should be used in the event an SARADCv2 without a reset ever makes it upstream.

There is a copy and paste bug here, it should be "reg_vref" instead of "reg_avdd". The "priv->reg_avdd" variable is zero so it ends up returning success.
