media: pwm-ir-tx: Depend on CONFIG_HIGH_RES_TIMERS

2024-02-01T12:49:39Z

Since commit 363d0e56285e ("media: pwm-ir-tx: Trigger edges from hrtimer interrupt context"), pwm-ir-tx uses high resolution timers for IR signal generation when the pwm can be used from atomic context. Ensure they are available. Fixes: 363d0e56285e ("media: pwm-ir-tx: Trigger edges from hrtimer interrupt context") Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: remove ir-rx51 in favour of generic pwm-ir-tx

2023-09-27T07:40:02Z

The ir-rx51 is a pwm-based TX driver specific to the N900. This can be handled entirely by the generic pwm-ir-tx driver, and in fact the pwm-ir-tx driver has been compatible with ir-rx51 from the start. Note that the suspend code in the ir-rx51 driver is unnecessary, since during transmit, the process is not in interruptable sleep. The process is not put to sleep until the transmit completes.

media: add HAS_IOPORT dependencies

2023-06-28T09:09:25Z

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. We thus need to add HAS_IOPORT as dependency for those drivers using them.

media: rc: Drop obsolete dependencies on COMPILE_TEST

2023-01-22T07:36:35Z

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues. As a minor optimization, this also lets us drop of_match_ptr(), as we now know what it will resolve to, we might as well save cpp some work.

media: sir_ir: remove broken driver

2021-10-19T07:08:39Z

This driver is a port of the lirc_sir driver to rc-core. However, for this driver I could not find any hardware to test, so it was done without testing. This is a mistake. There are clear bugs in the code. For example the two arguments to ktime_us_delta() are reversed, which means the result is garbage. The driver has been in the kernel for four years, and noone has ever reported an issue. So, remove this driver. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: introduce Meson IR TX driver

2021-08-04T12:43:49Z

This patch adds the driver for Amlogic Meson IR transmitter. Some Amlogic SoCs such as A311D and T950D4 have IR transmitter (also called blaster) controller onboard. It is capable of sending IR signals with arbitrary carrier frequency and duty cycle. The driver supports 2 modulation clock sources: - xtal3 clock (xtal divided by 3) - 1us clock Signed-off-by: Viktor Prutyanov Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: clean up Kconfig dependencies

2021-05-21T13:06:04Z

I came across a randconfig build failure from one driver that only depends on CONFIG_USB_ARCH_HAS_HCD but fails when built without CONFIG_USB: ld: drivers/media/rc/ir_toy.o: in function `irtoy_disconnect': ir_toy.c:(.text+0x24): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x2c): undefined reference to `usb_free_urb' ld: ir_toy.c:(.text+0x34): undefined reference to `usb_kill_urb' ld: ir_toy.c:(.text+0x3c): undefined reference to `usb_free_urb' Upon a closer look, I find that a lot of the other drivers 'select USB' rather than stating 'depends on USB' as is common for most subsystems. I also find that all except one driver have an extra 'depends on RC_CORE' that is already implied by the top-level 'if RC_CORE' check. Clean up both by reducing the dependencies to the required set.
