The REP_DELAY setting on the input device is independent of hardware. This change should not change how to driver works (as it does a keydown/keyup and has no real repeat handling). Signed-off-by:

These two functions only make the logic in lirc_register_driver() harder to follow. (Note that almost no other driver calls kobject_set_name() on their cdev so I simply removed that part). Signed-off-by:

Always let the kernel decide what minor the lirc chardev gets. Signed-off-by:

David Härdeman authored
Merging the two means that lirc_allocate_buffer() is called before device_add() and cdev_add() which makes more sense. This also simplifies the locking slightly because lirc_allocate_buffer() will always be called with lirc_dev_lock held. Signed-off-by:

Every caller of lirc_register_driver() passes their own fops and there are no users of lirc_dev_fop_write() in the kernel tree. Thus we can make fops mandatory and remove lirc_dev_fop_write(). Signed-off-by:

out_sysfs is misleading, sysfs only comes into play after device_add(). Also, calling device_init() before the rest of struct dev is filled out is clearer. Signed-off-by:

RX -EPIPE failure with infinite loop and flooding of [ 2851.966506] mceusb 1-1.2:1.0: Error: urb status = -32 log message at 8000 messages per second. Bug trigger appears to be normal, but heavy, IR receiver use. Driver and Linux host become unusable after error. Also seen at https://sourceforge.net/p/lirc/mailman/message/34886165/ Fix: Message reports RX usb halt (stall) condition requiring usb_clear_halt() call in non-interrupt context to recover. Add driver workqueue call to perform this recovery based on method in use for the usbnet device driver. Signed-off-by:

On the Amlogic SoCs, the bootloader firmware can handle the IR hardware in order to Wake up or Power back the system when in suspend on shutdown mode. This patch switches the hardware configuration in a state usable by the firmware to permit powering the system back. Some vendor bootloader firmware were modified to switch to this configuration but it may not be the case for all available products. This patch was originally posted at [1].

Make use of the bitfield macros thus partially hiding the complexity of dealing with bitfields. The patch also includes a minor fix to REG0_RATE_MASK, so far it was set to bit 0..10, but according to the spec it's bit 0..11. [mchehab@s-opensource.com: readd REG1_MODE_SHIFT and REG2_MODE_SHIFT that got removed on the original patch, as this will be used on another patch] Signed-off-by:

As of commit bb475230 ("reset: make optional functions really optional"), the reset framework API calls use NULL pointers to describe optional, non-present reset controls. This allows to return errors from devm_reset_control_get_optional without special cases and to call reset_control_reset unconditionally. Signed-off-by:

The xc5000 driver should not be spinning waiting for an analog lock. The ioctl() should be returning immediately and the application is responsible for polling for lock status. This behavior isn't very visible in cases where you tune to a valid channel, since lock is usually achieved much faster than 400ms. However it is highly visible where doing things like changing video standards, which sends tuning request for a frequency that is almost never going to have an actual channel on it. Also fixup the return values to treat zero as success and an actual error code on error (to be consistent with other functions). Note this change has no practical effect at this time as none of the callers inspect the return value. Signed-off-by:

Only looking at the lock register causes the status to float between locked and not locked when there is no signal. So improve the logic to also examine the state of the FSC PLL, which results in the lock status being consistently reported. Signed-off-by:

The second highest bit in the register value is an indicator to do a register read, so remove it since now au8522_regread() inserts the bit automatically. Also remove a stray instance where we were actually trying to write to the I2C status register, which was actually a read. Signed-off-by:

The leading bit in register values is actually an indicator as to whether to perform a read or write, so remove the bit from the register values, since the au8522_writereg() is now responsible for adding this bit automatically. Signed-off-by:

The original code was based on my reverse engineering of an I2C trace of the Windows driver. Now that I know what the registers actually do, restructure the code a bit, removing some unneeded register programming and fixing the sequencing of operations. This reduces the time it takes to change inputs from 1300ms down to 600ms (as measured by "time v4l2-ctl -i 0") Note this does not address outstanding issues related to the management of the module clocks and power control for the various blocks, which will be done in a separate patch.
