S3C2416 fixes (gpiolib, SDHCI, compilation without FB device)

[Yauhen Kharuzhy]

This patch series fixes SDHCI on S3C2416. I got SD card working with this patches
and with patches for GPIO card detection support by Marek Szyprowski.

[PATCH 1/4] ARM: S3C24XX: Fix gpiolib support for ports K..M

[Yauhen Kharuzhy]

S3C2443 and S3C2416 has 12 GPIO banks (from A to M), increase
ARCH_NR_GPIOS for this architectures.

Also typo from previous commit has been fixed: CONFIG_CPU_S3C24XX
instead CONFIG_CPU_244X.

[PATCH 4/4] ARM: S3C2416: Add platform helpers for setup SDHCI

[Yauhen Kharuzhy]

Samsung S3C2416 has two SDHCI controllers compatible with other
Samsung's SoCs (S3C64XX, S5PC100 etc...).

Add required platform setup code that the devices can be used with
sdhci-s3c driver.

would be nice to provide more accurate link to information source (document
version, page).
And there is a bit tricky place: clock ids are swapped and names of helper
functions are not.
So, it's not clear which helper function corresponds to real physical SDHC
interface.

S3C2416 User's Manual, pages 238 (10-4) and 241 (10-7): GPE5-GPE10
correspond to SD0, GPL0-GPL3, GPL8-GPL9 --- to SD1. So all platform
devices and GPIO config functions have namas swapped versus datasheet.

We have HSMMC1 and HSMMC0 swapped due to historical reasons --- there are HSMMC
block in S3C2443 and HSMMC1 block in S3C2416 on same address. I am going
to revert this swapping later.

S3C2416 fixes (gpiolib, SDHCI, compilation without FB device)

Unfortunately I did not get SD card working with these patches. I'm 
using custom board, not SMDK2416, but SD slot connection and schematics 
are the same like in SMDK2416. I've tried to debug a bit this problem 
and this is what I got: kernel do detection of card insert/remove, 
driver prints messages:

s3c-sdhci s3c-sdhci.1: card inserted.
s3c-sdhci s3c-sdhci.1: card removed.

Then I put some printk in s3c-sdhci driver and MMC core and found that 
mmc_rescan() is called only once at startup and no more when 
inserting/removing SD card. Also mmc_rescan() stops at that point where 
mmc_power_up() is called and does not return. And mmc_power_up() stops 
where mmc_delay(10) is called and does not return too.
Every time when inserting/removing SD card only functions 
sdhci_tasklet_card() and mmc_detect_change() are called, and nothing 
happens. Kernel doesn't detect the card inserted.
Maybe this info could help to debug where the problem is - in my custom 
board or in your patches?

Darius.

Have you tried with polled card detection method (SDHCI_CD_NONE)? If it
doesn't work I suspect something with the hardware. Checking with mmc debug
enabled might also help figuring this issue out.

yes, I've tried that, but didn't get sd card working. I got schematics 
from China manufacturer, SD card connection is the same like in 
smdk2416. with mmc debug enabled I found that SD card is detected when 
inserted or removed, but after detection card initialisation is not 
performed.

Does it work without my patches or with other Linux kernel? You can try to 
check the custom Linux 2.6.29 from 
git://git.kernel.org/pub/scm/linux/kernel/git/kki_ap/linux-2.6-samsung.git

I would like to know whether my patches cause the problem or there is some
kind of hardware issue with your board.

I did try with and without your patches. First, I applied only s3c2416 
realated patches from Yauhen, then I've added your patches, but nothing 
changed.

Oh, ok...maybe mini6410 and real6410? ;-)

yes. while talking about this -  what is state of my s3c64xx patches for next?
