[ Upstream commit 1017560164b6bbcbc93579266926e6e96675262a ]
Christian reports that 4K output using YUV420 encoding fails with the following error: Fatal Error, invalid HDMI vclk freq 593406
Modetest shows the following: 3840x2160 59.94 3840 4016 4104 4400 2160 2168 2178 2250 593407 flags: xxxx, xxxx, drm calculated value -------------------------------------^
This indicates that there's a (1kHz) mismatch between the clock calculated by the drm framework and the meson driver.
Relevant function call stack: (drm framework) -> meson_encoder_hdmi_atomic_enable() -> meson_encoder_hdmi_set_vclk() -> meson_vclk_setup()
The video clock requested by the drm framework is 593407kHz. This is passed by meson_encoder_hdmi_atomic_enable() to meson_encoder_hdmi_set_vclk() and the following formula is applied: - the frequency is halved (which would be 296703.5kHz) and rounded down to the next full integer, which is 296703kHz - TMDS clock is calculated (296703kHz * 10) - video encoder clock is calculated - this needs to match a table from meson_vclk.c and so it doubles the previously halved value again (resulting in 593406kHz) - meson_vclk_setup() can't find (either directly, or by deriving it from 594000kHz * 1000 / 1001 and rounding to the closest integer value - which is 593407kHz as originally requested by the drm framework) a matching clock in it's internal table and errors out with "invalid HDMI vclk freq"
Fix the division precision by switching the whole meson driver to use unsigned long long (64-bit) Hz values for clock frequencies instead of unsigned int (32-bit) kHz to fix the rouding error.
