Subject: [PATCH v2 16/33] ARM: davinci: aintc: use the new config structure
Date: Fri, 8 Feb 2019 18:34:41 +0100 [thread overview]
Message-ID: <20190208173458.4801-17-brgl@bgdev.pl> (raw)
In-Reply-To: <20190208173458.4801-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Modify the aintc driver to take all its configuration from the new
config structure. Stop referencing davinci_soc_info in any way.
Move the declaration for davinci_aintc_init() to irq-davinci-aintc.h
and make it take the new config structure as parameter. Convert all
users to the new version.
