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:

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 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.

Some stray lines got inserted into the driver when I reverse engineered the I2C traffic (at the time I didn't know what the registers did). It turns up these registers muck with the onboard I2C master, which we don't use since we instead use the I2C gate. Remove the lines which can actually interfere with the operation of the bus.

Since we don't suppoort sliced VBI with the au0828/au8522, there is no need to configure the au8522 VBI slicer, which because of the coefficients requires a large amount of i2c traffic.

In 'commit 295ab497 ("[media] media: platform: pxa_camera: make printk consistent")' a pointer to the device structure in mclk_get_divisor() was changed to pcdev_to_dev(pcdev). The pointer used by pcdev_to_dev() is still uninitialized during the call to mclk_get_divisor() as it happens in v4l2_device_register() at the end of the probe. The dev_warn and dev_dbg caused a line in the log: (NULL device *): Limiting master clock to 26000000 Fix this by using an initialized pointer from the platform_device (as before the old patch).

During the transfer from the soc_camera a test in pxa_mbus_image_size() got removed. Without it any PXA_MBUS_LAYOUT_PACKED format causes either the return of a wrong value (PXA_MBUS_PACKING_2X8_PADHI doubles the correct value) or EINVAL (PXA_MBUS_PACKING_NONE and PXA_MBUS_PACKING_EXTEND16).
