[U-Boot] [PATCH] Add inverted clock polarity support for Atmel LCD driver

[U-Boot] [PATCH] Add inverted clock polarity support for Atmel LCD driver

[Dimitar Dimitrov]

This is my third try for Olimex SAM9-L9260/61 board support patches. 

Here follows the first patch.
---

Boards utilizing the Atmel LCD driver can now specify that the LCD clock must
be inverted by defining the macro CONFIG_LCD_INVERTED_CLOCK.

[U-Boot] [PATCH 02/03 v3] Add support for Olimex SAM9-L9261 SBC

[Dimitar Dimitrov]

The SAM9-L9261 board support is based on code for AT91SAM9261EK. Networking
is missing and will be added after the DM9000 support for AT91 boards is
fixed to comply with U-Boot guide-lines.

[U-Boot] [PATCH 03/03 v3] Add support for Olimex SAM9-L9260 SBC

[Dimitar Dimitrov]

The SAM9-L9260 board support is based on code for AT91SAM9260EK. Networking
is missing and will be added after the MACB support for AT91 boards is
fixed to comply with U-Boot guide-lines.

same as 9261
could you regenerate it with

[U-Boot] [PATCH] Add inverted clock polarity support for Atmel LCD driver

actually the "vl_sync" is supposed to contain HSYNC and VSYNC
polarity flags and not the dot clock polarity. The Linux driver in
mainline uses var.sync for this purpose too, and doesn't set
inverted dot clock polarity at all.
This definition in struct vidinfo for Atmel LCD
	/* LCD configuration register */
        u_long vl_sync;         /* Horizontal / vertical sync */
        u_long vl_bpix;         /* Bits per pixel, 0 = 1, 1 = 2, 2 = 4, 3 = 8,
				 4 = 16 */
        u_long vl_tft;          /* 0 = passive, 1 = TFT */

is confusing. If these fields are supposed to contain flags
for LCD configuration register LCDCON2 then we should define
only one "u_long lcdcon2" field containing all the flags/fields
for sync polarity, bpp, clock polarity, scan mode, display type,
interface width, LCDD, LCDDEN polarities, LCDDOTCLK mode and memory
ordering format. We are wasting tree u_longs here and are not even
able to use half of the possible settings for LCDCON2 register.
I would rather fix the struct vidinfo for Atmel LCD so that
people could set needed flags in the board code, e.g.:

vidinfo_t panel_info = {
	...
	lcdcon2:	ATMEL_LCDC_INVLINE_INVERTED |
                        ATMEL_LCDC_INVFRAME_INVERTED |
			ATMEL_LCDC_INVCLK_INVERTED;
	...
}

I don't have the Atmel hardware to test/fix this change however.

Best regards,
Anatolij

I disagree here we must not make the panel_info atmel specific that way
we can add fields to pass atmel specific info which are pass via
struct atmel_lcdfb_info in Linux
But we need to be sync with linux as possible to simplify port and bugfix.

btw on Linux you do not specify it directly you specific this
FB_SYNC_HOR_HIGH_ACT	=> ATMEL_LCDC_INVLINE_INVERTED
FB_SYNC_VERT_HIGH_ACT	=> ATMEL_LCDC_INVFRAME_INVERTED

now i removed this patch from u-boot-video due to NACK from

I think we are stillw aiting for a re-submit of this patch after
cleaning up?

I can regenerate the patches for the latest GIT. If someone is willing to try them please let me know. 

Unfortunately I don't have the boards anymore so I can't verify that the new patches and new u-boot will work. That's why I avoid resubmission in this RC window.

Dimitar

Please clean up and resubmit, and mark the patches as "for `next'" so
we know they should go into the "next" branch.  Thanks in advance.
