Subject: [PATCH v3] platform/x86: ideapad-laptop: switch platform profiles using thermal management key

Ideapad laptops have thermal management or performance mode switch key
(Fn + Q). They report KEY_PROG4.

If supported, cycle platform profiles instead.

Tested on Yoga7 14ARB7.

Changes in v3:
- add dytc_profile_cycle function
Changes in v2:
- only switch platform profiles if supported, otherwise keep the
behavior.

Cycling is done through modulo.

Quick and dirty example:

static int profiles[] = {
PLATFORM_PROFILE_LOW_POWER,
PLATFORM_PROFILE_BALANCED,
PLATFORM_PROFILE_PERFORMANCE
};

static int current_profile_index = 0;

static void dytc_profile_cycle(struct ideapad_private *priv)
{
current_profile_index++

current_profile_index =
current_profile_index % ARRAY_SIZE(profiles);

dytc_profile_set(&priv->dytc->pprof,
profiles[current_profile_index]);

platform_profile_notify();
}

Thanks for your suggestions. I thought about it.
It would make this module complicated, but something like this fits
well in the platform_profile module.
I will implement the cycle there in v4.

Best regards,
