db6668d83a fbdev: sh_mobile_hdmi: 32bit register access support
Latest SuperH HDMI allows 32bit access only.
But the data is 8bit. So, we can keep compatibility by switching 8/32 bit access.

c36940e678 fbdev: sh_mobile_hdmi: add support for more precise HDMI clock configuration
The HDMI clock has to be reconfigured for different video modes. However, the
precision of the supplying SoC clock on SH-Mobile systems is often
insufficient. This patch allows to additionally reconfigure the parent clock
to achieve the optimal HDMI clock frequency, in case this is supported by the
platform.

dec6aa49ab fbdev: sh_mobile_hdmi: modify flags name to more specific
This patch solve below report from Guennadi

1)

> +/* Audio source select */
> +#define HDMI_SRC_MASK		(0xF << 0)
> +#define HDMI_SRC_I2S		(0 << 0) /* default */
> +#define HDMI_SRC_SPDIF		(1 << 0)
> +#define HDMI_SRC_DSD		(2 << 0)
> +#define HDMI_SRC_HBR		(3 << 0)

I would be more specific with these macro names, i.e., include "AUDIO" or
"SND" or something similar in them, e.g., HDMI_AUDIO_SRC_I2S.

2)

> +	case HDMI_SRC_I2S:
> +		data = (0x0 << 3);
> +		break;
> +	case HDMI_SRC_SPDIF:
> +		data = (0x1 << 3);
> +		break;
> +	case HDMI_SRC_DSD:
> +		data = (0x2 << 3);
> +		break;
> +	case HDMI_SRC_HBR:
> +		data = (0x3 << 3);

In all above cases parenthesis are superfluous.

6011bdeaa6 fbdev: sh-mobile: HDMI support for SH-Mobile SoCs
Some SH-Mobile SoCs have an HDMI controller and a PHY, attached to one of their
LCDC interfaces. This patch adds a preliminary static support for such
controllers, this means, that only the 720p mode is handled ATM. Support for
more modes and a dynamic switching between them will be added by a follow up
patch.
