HT mode is not supported by imx6ul

Hello,

While reading the imx6ul referance manual, observed HT mode is not supported by imx6ul. ( chapter 20 , ECSPI section)

This is 1 bit field ECSPIx_CONREG register.

{ Hardware Trigger Enable. This bit is used in master mode only. It enables hardware trigger (HT) mode.

Note, HT mode is not supported by this product.

0 Disable HT mode.

1 Enable HT mode. }

For what purpose this bit is used ? Is this related to native chip select, as native chip select driven by hardware only.

Hello,

ECSPI module (IP) in i.MX6 does not have HT implemented, since

there are no corresponding trigger inputs.

Have a great day,
Yuri
