From b9626f32876debc356fadb6e19aebcfe9d70c5ff Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Mon, 1 Dec 2014 19:32:51 +0100 Subject: tpm/tpm_i2c_stm_st33: Add new tpm_stm_dev structure and remove tpm_i2c_buffer[0], [1] buffer. In order to clean big buffers in st33zp24_platform_data structure, replace with tpm_stm_dev for driver internal usage. As only one buffer is really necessary replace with buf field. In the mean time move tpm_i2c_stm_st33.h to include/linux/platform_data.

After driver initialization, the serirq signal is always used through interrupt and never with gpio kernel API. The irq can then be initialized during the platform_data definition within the client->irq pin.
