Please group same/similar inclusion together like following.
<linux/...> <asm/...> then <mach/...> or <plat/...>

In other words, please add your <plat/ts.h> inclusion after other <plat/...>

How about to use tab between member and = like following?

static struct s3c2410_ts_mach_info gta02_ts_info = {
	.delay			= 10000,
	.presc			= 0xff, /* slow as we can go */
	.oversampling_shift	= 2,
};

No need to build plat-samsung/dev-adc.c for this?
If you want to add '&s3c_deivce_adc', should add 'select SAMSUNG_DEV_ADC'
into "config MACH_NEO1973_GTA02".

'select SAMSUNG_DEV_TS'

Same as above. 'select SAMSUNG_DEV_TS' should be added for
plat-samsung/dev-ts.c.
