[PATCH 0/5] [input] tsc2005 cleanup

Hi,

The following patches simplify and cleanup the tsc2005 touchscreen driver.
Apart from making the driver more readable, the direct usage of SPI has been
reduced to one function, so that tsc2004 support may be addable now (see [0]).

Changes since PATCHv1 [1]:
 * Avoid mixing spi_*_drvdata() and dev_*_drvdata() by converting
   all spi_*_drvdata() to  dev_*_drvdata()
 * Add new patch fixing the indent of TSC2005's Kconfig entry
 * Select REGMAP_SPI in TSC2005's Kconfig entry
 * Use optional gpiod and regulator API, so that the DT check can
   be removed
 * Set TSC2005_REG_PND0 on regmap writes, since it has also been
   used before the regmap conversion.
