2021-08-04media: rc: introduce Meson IR TX driverViktor Prutyanov3-0/+418
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 <[email protected]> Signed-off-by: Sean Young <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2021-06-24media, bpf: Do not copy more entries than user space requestedSean Young1-1/+2
The syscall bpf(BPF_PROG_QUERY, &attr) should use the prog_cnt field to see how many entries user space provided and return ENOSPC if there are more programs than that. Before this patch, this is not checked and ENOSPC is never returned. Note that one lirc device is limited to 64 bpf programs, and user space I'm aware of -- ir-keytable -- always gives enough space for 64 entries already. However, we should not copy program ids than are requested.

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.

2021-03-11media: rc: compile rc-cec.c into rc-coreHans Verkuil4-18/+18
The rc-cec keymap is unusual in that it can't be built as a module, instead it is registered directly in rc-main.c if CONFIG_MEDIA_CEC_RC is set. This is because it can be called from drm_dp_cec_set_edid() via cec_register_adapter() in an asynchronous context, and it is not allowed to use request_module() to load rc-cec.ko in that case. Trying to do so results in a 'WARN_ON_ONCE(wait && current_is_async())'. Since this keymap is only used if CONFIG_MEDIA_CEC_RC is set, we just compile this keymap into the rc-core module and never as a separate module.

2021-01-27media: sunxi-cir: Factor out hardware initializationSamuel Holland1-54/+74
In preparation for adding suspend/resume hooks, factor out the hardware initialization from the driver probe/remove functions. The timeout programmed during init is taken from the `struct rc_dev` so it is maintained across an exit/init cycle. This resolves some trivial issues with the probe function: throwing away the error from clk_prepare_enable and using the wrong type for the temporary register value. It also fixes the order of the remove function to unregister the RC device before turning off the hardware. This prevents userspace from triggering register writes (via LIRC_SET_REC_TIMEOUT) while the hardware is disabled.

Only one register, SUNXI_IR_CIR_REG, is accessed from outside the interrupt handler, and that register is not accessed from inside it. As there is no overlap between different contexts, no lock is needed.

2021-01-14media: mceusb: Fix potential out-of-bounds shiftJames Reynolds1-1/+1
When processing a MCE_RSP_GETPORTSTATUS command, the bit index to set in ir->txports_cabled comes from response data, and isn't validated. As ir->txports_cabled is a u8, nothing should be done if the bit index is greater than 7.

Commit 528222d853f92 ("media: rc: harmonize infrared durations to microseconds") missed to switch the min_timeout calculation from ns to us. This resulted in a minimum timeout of 1.2 seconds instead of 1.2ms, leading to large delays and long key repeats. Fix this by applying proper ns->us conversion.

2021-01-11media: rc: fix timeout handling after switch to microsecond durationsMatthias Reichl3-4/+4
Commit 528222d853f92 ("media: rc: harmonize infrared durations to microseconds") missed to switch some timeout calculations from nanoseconds to microseconds. This resulted in spurious key_up+key_down events at the last scancode if the rc device uses a long timeout (eg 100ms on nuvoton-cir) as the device timeout wasn't properly accounted for in the keyup timeout calculation. Fix this by applying the proper conversion functions.

Since commit 528222d853f9 ("media: rc: harmonize infrared durations to microseconds"), the calculation of the chk period is wrong. As a result, all reported IR will have incorrect timings. Now that the calculations are done in microseconds rather than nanoseconds, we can fold the calculations in a simpler form with less rounding error.
